NAME¶
rsnapshot - remote filesystem snapshot utilitySYNOPSIS¶
rsnapshot [-vtxqVD] [-c cfgfile] [command] [args]DESCRIPTION¶
rsnapshot is a filesystem snapshot utility. It can take incremental snapshots of local and remote filesystems for any number of machines. Local filesystem snapshots are handled with rsync(1). Secure remote connections are handled with rsync over ssh(1), while anonymous rsync connections simply use an rsync server. Both remote and local transfers depend on rsync. rsnapshot saves much more disk space than you might imagine. The amount of space required is roughly the size of one full backup, plus a copy of each additional file that is changed. rsnapshot makes extensive use of hard links, so if the file doesn't change, the next snapshot is simply a hard link to the exact same file. rsnapshot will typically be invoked as root by a cron job, or series of cron jobs. It is possible, however, to run as any arbitrary user with an alternate configuration file. All important options are specified in a configuration file, which is located by default at /etc/rsnapshot.conf. An alternate file can be specified on the command line. There are also additional options which can be passed on the command line. The command line options are as follows:-v verbose, show shell commands being executed
-t test, show shell commands that would be executed
-c path to alternate config file
-x one filesystem, don't cross partitions within each backup point
-q quiet, suppress non-fatal warnings
-V same as -v, but with more detail
-D a firehose of diagnostic information
CONFIGURATION¶
/etc/rsnapshot.conf is the default configuration file. All parameters in this file must be separated by tabs. /usr/share/doc/rsnapshot/examples/rsnapshot.conf.default.gz can be used as a reference. It is recommended that you copy /usr/share/doc/rsnapshot/examples/rsnapshot.conf.default.gz to /etc/rsnapshot.conf, and then modify /etc/rsnapshot.conf to suit your needs. Long lines may be split over several lines. "Continuation" lines must begin with a space or a tab character. Continuation lines will have all leading and trailing whitespace stripped off, and then be appended with an intervening tab character to the previous line when the configuation file is parsed. Here is a list of allowed parameters:config_version Config file version (required).
Default is 1.2
snapshot_root Local filesystem path to save all snapshots
include_conf Include another file in the configuration at this point.
This is recursive, but you may need to be careful about
paths when specifying which file to include. We check to see if the file you
have specified is readable, and will yell an error if it isn't. We recommend
using a full path. As a special case, include_conf's value may be enclosed in
`backticks` in which case it will be executed and whatever it spits to STDOUT
will be included in the configuration. Note that shell meta-characters may be
interpreted.
no_create_root If set to 1, rsnapshot won't create snapshot_root
directory
cmd_rsync Full path to rsync (required)
cmd_ssh Full path to ssh (optional)
cmd_cp Full path to cp (optional, but must be GNU version)
If you are using Linux, you should uncomment cmd_cp. If
you are using a platform which does not have GNU cp, you should leave cmd_cp
commented out.
With GNU cp, rsnapshot can take care of both normal files and special files
(such as FIFOs, sockets, and block/character devices) in one pass.
If cmd_cp is disabled, rsnapshot will use its own built-in function,
native_cp_al() to backup up regular files and directories. This will
then be followed up by a separate call to rsync, to move the special files
over (assuming there are any).
cmd_rm Full path to rm (optional)
cmd_logger Full path to logger (optional, for syslog support)
cmd_du Full path to du (optional, for disk usage reports)
cmd_rsnapshot_diff Full path to rsnapshot-diff (optional)
cmd_preexec
Full path (plus any arguments) to preexec script
(optional). This script will run immediately before each backup operation (but
not any rotations).
cmd_postexec
Full path (plus any arguments) to postexec script
(optional). This script will run immediately after each backup operation (but
not any rotations).
linux_lvm_cmd_lvcreate
linux_lvm_cmd_lvremove
linux_lvm_cmd_mount
linux_lvm_cmd_umount
Paths to lvcreate, lvremove, mount and umount commands,
for use with Linux LVMs. The lvcreate, lvremove, mount and umount commands are
required for managing snapshots of LVM volumes and are otherwise
optional.
retain [name] [number]
"name" refers to the name of this backup level
(e.g., hourly, daily, so also called the 'interval'). "number" is
the number of snapshots for this type of interval that will be retained. The
value of "name" will be the command passed to rsnapshot to
perform this type of backup.
A deprecated alias for 'retain' is 'interval'.
Example: retain hourly 6
[root@localhost]# rsnapshot hourly
For this example, every time this is run, the following will happen:
<snapshot_root>/hourly.5/ will be deleted, if it exists.
<snapshot_root>/hourly.{1,2,3,4} will all be rotated +1, if they exist.
<snapshot_root>/hourly.0/ will be copied to
<snapshot_root>/hourly.1/ using hard links.
Each backup point (explained below) will then be rsynced to the corresponding
directories in <snapshot_root>/hourly.0/
Backup levels must be specified in the config file in order, from most frequent
to least frequent. The first entry is the one which will be synced with the
backup points. The subsequent backup levels (e.g., daily, weekly, etc) simply
rotate, with each higher backup level pulling from the one below it for its .0
directory.
Example:
retain hourly 6
retain daily 7
retain weekly 4
daily.0/ will be moved from hourly.5/, and weekly.0/ will be copied from
daily.6/
hourly.0/ will be rsynced directly from the filesystem.
link_dest 1
If your version of rsync supports --link-dest (2.5.7 or
newer), you can enable this to let rsync handle some things that GNU cp or the
built-in subroutines would otherwise do. Enabling this makes rsnapshot take a
slightly more complicated code branch, but it's the best way to support
special files on non-Linux systems.
sync_first 1
sync_first changes the behaviour of rsnapshot. When this
is enabled, all calls to rsnapshot with various backup levels simply rotate
files. All backups are handled by calling rsnapshot with the "sync"
argument. The synced files are stored in a ".sync" directory under
the snapshot_root.
This allows better recovery in the event that rsnapshot is interrupted in the
middle of a sync operation, since the sync step and rotation steps are
separated. This also means that you can easily run "rsnapshot sync"
on the command line without fear of forcing all the other directories to
rotate up. This benefit comes at the cost of one more snapshot worth of disk
space. The default is 0 (off).
verbose 2
The amount of information to print out when the program
is run. Allowed values are 1 through 5. The default is 2.
1 Quiet Show fatal errors only 2 Default Show warnings and errors 3 Verbose Show equivalent shell commands being executed 4 Extra Verbose Same as verbose, but with more detail 5 Debug All kinds of information
loglevel 3
This number means the same thing as verbose above,
but it determines how much data is written to the logfile, if one is being
written.
The only thing missing from this at the higher levels is the direct output from
rsync. We hope to add support for this in a future release.
logfile /var/log/rsnapshot
Full filesystem path to the rsnapshot log file. If this
is defined, a log file will be written, with the amount of data being
controlled by loglevel. If this is commented out, no log file will be
written.
include [file-name-pattern]
This gets passed directly to rsync using the --include
directive. This parameter can be specified as many times as needed, with one
pattern defined per line. See the rsync(1) man page for the
syntax.
exclude [file-name-pattern]
This gets passed directly to rsync using the --exclude
directive. This parameter can be specified as many times as needed, with one
pattern defined per line. See the rsync(1) man page for the
syntax.
include_file /path/to/include/file
This gets passed directly to rsync using the
--include-from directive. See the rsync(1) man page for the
syntax.
exclude_file /path/to/exclude/file
This gets passed directly to rsync using the
--exclude-from directive. See the rsync(1) man page for the
syntax.
rsync_short_args -a
List of short arguments to pass to rsync. If not
specified, "-a" is the default. Please note that these must be all
next to each other. For example, "-az" is valid, while "-a
-z" is not.
"-a" is rsync's "archive mode" which tells it to copy as
much of the filesystem metadata as it can for each file. This specifically
does *not* include information about hard links, as that would greatly
increase rsync's memory usage and slow it down. If you need to preserve hard
links in your backups, then add "H" to this.
rsync_long_args --delete --numeric-ids --relative --delete-excluded
List of long arguments to pass to rsync. Beginning with
rsnapshot 1.2.0, this default has changed. In previous versions, the default
values were
--delete --numeric-idsStarting with version 1.2.0, the default values are
--delete --numeric-ids --relative --delete-excludedThis directly affects how the destination paths in your backup points are constructed. Depending on what behaviour you want, you can explicitly set the values to make the program behave like the old version or the current version. The newer settings are recommended if you're just starting. If you are upgrading, read the upgrade guide in the INSTALL file in the source distribution for more information. Quotes are permitted in rsync_long_args, eg --rsync-path="sudo /usr/bin/rsync". You may use either single (') or double (") quotes, but nested quotes (including mixed nested quotes) are not permitted. Similar quoting is also allowed in per-backup-point rsync_long_args.
ssh_args -p 22
Arguments to be passed to ssh. If not specified, the
default is none.
du_args -csh
Arguments to be passed to du. If not specified, the
default is -csh. GNU du supports -csh, BSD du supports -csk, Solaris du
doesn't support -c at all. The GNU version is recommended, since it offers the
most features.
lockfile /var/run/rsnapshot.pid
stop_on_stale_lockfile 0
Lockfile to use when rsnapshot is run. This prevents a
second invocation from clobbering the first one. If not specified, no lock
file is used. Make sure to use a directory that is not world writeable for
security reasons. Use of a lock file is strongly recommended.
If a lockfile exists when rsnapshot starts, it will try to read the file and
stop with an error if it can't. If it *can* read the file, it sees if a
process exists with the PID noted in the file. If it does, rsnapshot stops
with an error message. If there is no process with that PID, then we assume
that the lockfile is stale and ignore it *unless* stop_on_stale_lockfile is
set to 1 in which case we stop.
stop_on_stale_lockfile defaults to 0.
one_fs 1
Prevents rsync from crossing filesystem partitions.
Setting this to a value of 1 enables this feature. 0 turns it off. This
parameter is optional. The default is 0 (off).
use_lazy_deletes 1
Changes default behavior of rsnapshot and does not
initially remove the oldest snapshot. Instead it moves that directory to
_delete.[processid] and continues as normal. Once the backup has been
completed, the lockfile will be removed before rsnapshot starts deleting the
directory.
Enabling this means that snapshots get taken sooner (since the delete doesn't
come first), and any other rsnapshot processes are allowed to start while the
final delete is happening. This benefit comes at the cost of using more disk
space. The default is 0 (off).
The details of how this works have changed in rsnapshot version 1.3.1.
Originally you could only ever have one .delete directory per backup level.
Now you can have many, so if your next (eg) hourly backup kicks off while the
previous one is still doing a lazy delete you may temporarily have extra
_delete directories hanging around.
linux_lvm_snapshotsize 2G
LVM snapshot(s) size (lvcreate --size option).
linux_lvm_snapshotname rsnapshot
Name to be used when creating the LVM logical volume
snapshot(s) (lvcreate --name option).
linux_lvm_vgpath /dev
Path to the LVM Volume Groups.
linux_lvm_mountpath /mnt/lvm-snapshot
Mount point to use to temporarily mount the
snapshot(s).
UPGRADE NOTICE:
If you have used an older version of rsnapshot, you might
notice that the destination paths on the backup points have changed. Please
read the INSTALL file in the source distribution for upgrade options.
backup /etc/ localhost/
backup root@example.com:/etc/ example.com/
backup rsync://example.com/path2/ example.com/
backup /var/ localhost/ one_fs=1
backup lvm://vg0/home/path2/ lvm-vg0/
backup_script /usr/local/bin/backup_pgsql.sh pgsql_backup/
Examples:
backup /etc/ localhost/
Backs up /etc/ to
<snapshot_root>/<retain>.0/localhost/etc/ using rsync on the local
filesystem
backup /usr/local/ localhost/
Backs up /usr/local/ to
<snapshot_root>/<retain>.0/localhost/usr/local/ using rsync on the
local filesystem
backup root@example.com:/etc/ example.com/
Backs up root@example.com:/etc/ to
<snapshot_root>/<retain>.0/example.com/etc/ using rsync over
ssh
backup root@example.com:/usr/local/ example.com/
Backs up root@example.com:/usr/local/ to
<snapshot_root>/<retain>.0/example.com/usr/local/ using rsync over
ssh
backup rsync://example.com/pub/ example.com/pub/
Backs up rsync://example.com/pub/ to
<snapshot_root>/<retain>.0/example.com/pub/ using an anonymous
rsync server. Please note that unlike backing up local paths and using rsync
over ssh, rsync servers have "modules", which are top level
directories that are exported. Therefore, the module should also be specified
in the destination path, as shown in the example above (the pub/ directory at
the end).
backup /var/ localhost/ one_fs=1
This is the same as the other examples, but notice the
fourth column. This is how you specify per-backup-point options to over-ride
global settings. This extra parameter can take several options, separated by
commas.
It is most useful when specifying per-backup rsync excludes thus:
backup root@somehost:/ somehost +rsync_long_args=--exclude=/var/spool/
Note the + sign. That tells rsnapshot to add to the list of arguments to
pass to rsync instead of replacing the list.
backup lvm://vg0/home/path2/ lvm-vg0/
Backs up the LVM logical volume called home, of volume
group vg0, to <snapshot_root>/<interval>.0/lvm-vg0/. Will create,
mount, backup, unmount and remove an LVM snapshot for each lvm:// entry.
backup_script /usr/local/bin/backup_database.sh db_backup/
In this example, we specify a script or program to run.
This script should simply create files and/or directories in its current
working directory. rsnapshot will then take that output and move it into the
directory specified in the third column.
Please note that whatever is in the destination directory will be completely
deleted and recreated. For this reason, rsnapshot prevents you from specifying
a destination directory for a backup_script that will clobber other backups.
So in this example, say the backup_database.sh script simply runs a command
like:
#!/bin/sh
mysqldump -uusername mydatabase > mydatabase.sql
chmod u=r,go= mydatabase.sql # r-------- (0400)
rsnapshot will take the generated "mydatabase.sql" file and move it
into the <snapshot_root>/<retain>.0/db_backup/ directory. On
subsequent runs, rsnapshot checks the differences between the files created
against the previous files. If the backup script generates the same output on
the next run, the files will be hard linked against the previous ones, and no
additional disk space will be taken up.
Remember that tabs must separate all elements, and that there must be a trailing
slash on the end of every directory.
A hash mark (#) on the beginning of a line is treated as a comment.
Putting it all together (an example file):
# THIS IS A COMMENT, REMEMBER TABS MUST SEPARATE ALL ELEMENTS config_version 1.2 snapshot_root /.snapshots/ cmd_rsync /usr/bin/rsync cmd_ssh /usr/bin/ssh #cmd_cp /bin/cp cmd_rm /bin/rm cmd_logger /usr/bin/logger cmd_du /usr/bin/du linux_lvm_cmd_lvcreate /sbin/lvcreate linux_lvm_cmd_lvremove /sbin/lvremove linux_lvm_cmd_mount /bin/mount linux_lvm_cmd_umount /bin/umount linux_lvm_snapshotsize 2G linux_lvm_snapshotname rsnapshot linux_lvm_vgpath /dev linux_lvm_mountpath /mnt/lvm-snapshot retain hourly 6 retain daily 7 retain weekly 7 retain monthly 3 backup /etc/ localhost/ backup /home/ localhost/ backup_script /usr/local/bin/backup_mysql.sh mysql_backup/ backup root@foo.com:/etc/ foo.com/ backup root@foo.com:/home/ foo.com/ backup root@mail.foo.com:/home/ mail.foo.com/ backup rsync://example.com/pub/ example.com/pub/ backup lvm://vg0/xen-home/ lvm-vg0/xen-home/
USAGE¶
rsnapshot can be used by any user, but for system-wide backups you will probably want to run it as root. Since backups usually get neglected if human intervention is required, the preferred way is to run it from cron. When you are first setting up your backups, you will probably also want to run it from the command line once or twice to get a feel for what it's doing. Here is an example crontab entry, assuming that backup levels hourly, daily, weekly and monthly have been defined in /etc/rsnapshot.conf0 */4 * * * /usr/bin/rsnapshot hourly
50 23 * * * /usr/bin/rsnapshot daily
40 23 * * 6 /usr/bin/rsnapshot weekly
30 23 1 * * /usr/bin/rsnapshot monthly
This example will do the following:
6 hourly backups a day (once every 4 hours, at
0,4,8,12,16,20)
1 daily backup every day, at 11:50PM
1 weekly backup every week, at 11:40PM, on Saturdays (6th day of week)
1 monthly backup every month, at 11:30PM on the 1st day of the month
It is usually a good idea to schedule the larger backup levels to run a bit
before the lower ones. For example, in the crontab above, notice that
"daily" runs 10 minutes before "hourly". The main reason
for this is that the daily rotate will pull out the oldest hourly and make
that the youngest daily (which means that the next hourly rotate will not need
to delete the oldest hourly), which is more efficient. A secondary reason is
that it is harder to predict how long the lowest backup level will take, since
it needs to actually do an rsync of the source as well as the rotate that all
backups do.
If rsnapshot takes longer than 10 minutes to do the "daily" rotate
(which usually includes deleting the oldest daily snapshot), then you should
increase the time between the backup levels. Otherwise (assuming you have set
the lockfile parameter, as is recommended) your hourly snapshot will
fail sometimes because the daily still has the lock.
Remember that these are just the times that the program runs. To set the number
of backups stored, set the retain numbers in /etc/rsnapshot.conf
To check the disk space used by rsnapshot, you can call it with the
"du" argument.
For example:
rsnapshot du
This will show you exactly how much disk space is taken up in the snapshot root.
This feature requires the UNIX du command to be installed on your
system, for it to support the "-csh" command line arguments, and to
be in your path. You can also override your path settings and the flags passed
to du using the cmd_du and du_args parameters.
It is also possible to pass a relative file path as a second argument, to get a
report on a particular file or subdirectory.
rsnapshot du localhost/home/
The GNU version of "du" is preferred. The BSD version works well also,
but does not support the -h flag (use -k instead, to see the totals in
kilobytes). Other versions of "du", such as Solaris, may not work at
all.
To check the differences between two directories, call rsnapshot with the
"diff" argument, followed by two backup levels or directory paths.
For example:
rsnapshot diff daily.0 daily.1
rsnapshot diff daily.0/localhost/etc daily.1/localhost/etc
rsnapshot diff /.snapshots/daily.0 /.snapshots/daily.1
This will call the rsnapshot-diff program, which will scan both directories
looking for differences (based on hard links).
rsnapshot sync
When sync_first is enabled, rsnapshot must first
be called with the sync argument, followed by the other usual cron
entries. The sync should happen as the lowest, most frequent backup level, and
right before. For example:
0 */4 * * * /usr/bin/rsnapshot sync &&
/usr/bin/rsnapshot hourly
50 23 * * * /usr/bin/rsnapshot daily
40 23 1,8,15,22 * * /usr/bin/rsnapshot weekly
30 23 1 * * /usr/bin/rsnapshot monthly
The sync operation simply runs rsync and all backup scripts. In this scenario,
all calls simply rotate directories, even the lowest backup level.
rsnapshot sync [dest]
When sync_first is enabled, all sync behaviour
happens during an additional sync step (see above). When using the sync
argument, it is also possible to specify a backup point destination as an
optional parameter. If this is done, only backup points sharing that
destination path will be synced.
For example, let's say that example.com is a destination path shared by one or
more of your backup points.
rsnapshot sync example.com
This command will only sync the files that normally get backed up into
example.com. It will NOT get any other backup points with slightly different
values (like example.com/etc/, for example). In order to sync example.com/etc,
you would need to run rsnapshot again, using example.com/etc as the optional
parameter.
EXIT VALUES¶
0 All operations completed successfully
1 A fatal error occurred
2 Some warnings occurred, but the backup still finished
FILES¶
/etc/rsnapshot.confSEE ALSO¶
rsync(1), ssh(1), logger(1), sshd(1), ssh-keygen(1), perl(1), cp(1), du(1), crontab(1)DIAGNOSTICS¶
Use the -t flag to see what commands would have been executed. This will show you the commands rsnapshot would try to run. There are a few minor differences (for example, not showing an attempt to remove the lockfile because it wasn't really created in the test), but should give you a very good idea what will happen. Using the -v, -V, and -D flags will print increasingly more information to STDOUT. Make sure you don't have spaces in the config file that you think are actually tabs. Much other weird behavior can probably be attributed to plain old file system permissions and ssh authentication issues.BUGS¶
Please report bugs (and other comments) to the rsnapshot-discuss mailing list: http://lists.sourceforge.net/lists/listinfo/rsnapshot-discussNOTES¶
Make sure your /etc/rsnapshot.conf file has all elements separated by tabs. See /usr/share/doc/rsnapshot/examples/rsnapshot.conf.default.gz for a working example file. Make sure you put a trailing slash on the end of all directory references. If you don't, you may have extra directories created in your snapshots. For more information on how the trailing slash is handled, see the rsync (1) manpage. Make sure to make the snapshot directory chmod 700 and owned by root (assuming backups are made by the root user). If the snapshot directory is readable by other users, they will be able to modify the snapshots containing their files, thus destroying the integrity of the snapshots. If you would like regular users to be able to restore their own backups, there are a number of ways this can be accomplished. One such scenario would be: Set snapshot_root to /.private/.snapshots in /etc/rsnapshot.conf Set the file permissions on these directories as follows:drwx------ /.private
drwxr-xr-x /.private/.snapshots
Export the /.private/.snapshots directory over read-only NFS, a read-only Samba
share, etc.
See the rsnapshot HOWTO for more information on making backups accessible to
non-privileged users.
For ssh to work unattended through cron, you will probably want to use public
key logins. Create an ssh key with no passphrase for root, and install the
public key on each machine you want to backup. If you are backing up system
files from remote machines, this probably means unattended root logins.
Another possibility is to create a second user on the machine just for
backups. Give the user a different name such as "rsnapshot", but
keep the UID and GID set to 0, to give root privileges. However, make logins
more restrictive, either through ssh configuration, or using an alternate
shell.
BE CAREFUL! If the private key is obtained by an attacker, they will have free
run of all the systems involved. If you are unclear on how to do this, see
ssh(1), sshd(1), and
ssh-keygen(1).
Backup scripts are run as the same user that rsnapshot is running as. Typically
this is root. Make sure that all of your backup scripts are only writable by
root, and that they don't call any other programs that aren't owned by root.
If you fail to do this, anyone who can write to the backup script or any
program it calls can fully take over the machine. Of course, this is not a
situation unique to rsnapshot.
By default, rsync transfers are done using the --numeric-ids option. This means
that user names and group names are ignored during transfers, but the UID/GID
information is kept intact. The assumption is that the backups will be
restored in the same environment they came from. Without this option,
restoring backups for multiple heterogeneous servers would be unmanageable. If
you are archiving snapshots with GNU tar, you may want to use the
--numeric-owner parameter. Also, keep a copy of the archived system's
/etc/passwd and /etc/group files handy for the UID/GID to name mapping.
If you remove backup points in the config file, the previously archived files
under those points will permanently stay in the snapshots directory unless you
remove the files yourself. If you want to conserve disk space, you will need
to go into the <snapshot_root> directory and manually remove the files
from the smallest backup level's ".0" directory.
For example, if you were previously backing up /home/ with a destination of
localhost/, and hourly is your smallest backup level, you would need to do the
following to reclaim that disk space:
rm -rf
<snapshot_root>/hourly.0/localhost/home/
Please note that the other snapshots previously made of /home/ will still be
using that disk space, but since the files are flushed out of hourly.0/, they
will no longer be copied to the subsequent directories, and will thus be
removed in due time as the rotations happen.
