\&\fBnbackup\fR allows making incremental backups of firebird databases. It also
allows database files to be locked for copying with \s-1OS\s0 tools like

.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-L\fR \fIdatabase\fR" 4
.IX Item "-L database"
Locks \fIdatabase\fR for filesystem copy.
.IP "\fB\-U\fR \fIdatabase\fR" 4
.IX Item "-U database"
Unlocks previously locked database.
.IP "\fB\-F\fR \fIdatabase\fR" 4
.IX Item "-F database"
Fixup \fIdatabase\fR after filesystem copy.
.IP "\fB\-B\fR \fIlevel\fR \fIdatabase\fR [\fIfilename\fR]" 4
.IX Item "-B level database [filename]"
Create incremental backup of level \fIlevel\fR. Level 0 means full backup. Level
\&\fIN\fR includes all the changes since the last backup of level \fIN\fR.
.IP "\fB\-R\fR \fIdatabase\fR [\fIfile0\fR [\fIfile1\fR...]]" 4
.IX Item "-R database [file0 [file1...]]"
Restore incremental backup. \fIfile0\fR is the level 0 backup, \fIfile1\fR is the
level 1 backup and so on.
