amdump - back up all disks in an Amanda configuration
amdump [--no-taper] [--exact-match] [-o configoption...] config [host [disk...]...]
Amdump is the main interface to the Amanda backup process. It loads the specified configuration and attempts to back up every disk specified by the disklist(5). Amdump is normally run by cron.
The command optionally takes a set of DLE specifications (see amanda-match(7)) to narrow the DLEs that will be dumped. All disks are dumped if no expressions are given.
If a file named hold exists in the configuration directory, amdump will wait until it is removed before starting the backups. This allows scheduled backups to be delayed when circumstances warrant, for example, if the tape device is being used for some other purpose. While waiting, amdump checks for the hold file every minute.
In some cases it is desirable to dump all Amanda clients to holding disk without writing anything to storage media. The --no-taper option instructs Amanda to not start the taper, and thus enter degraded mode immediately.
See the amanda(8) man page for more details about Amanda.
Here is a typical crontab entry. It runs amdump every weeknight at 1 a.m. as user bin:
0 1 * * 1-5 bin /usr/local/sbin/amdump daily
amdump: waiting for hold file to be removed
amdump: amdump or amflush is already running, or you must run amcleanup
The exit code of amdump is the ORed value of:
0 = success
1 = error
2 = a dle give strange message
4 = a dle failed
8 = Don't know the status of a dle (RESULT_MISSING in the report)
16 = tape error or no more tape
