incr_backup - run an incremental backup with the afbackup package.
incr_backup <options ... See: full_backup> [ -EH ] [ -Q <backup-level>
This program reads the client-side configuration file and runs an
incremental backup, i.e. all files and directories are saved, whose
modification time is later than the moment the previous backup (full or
incremental) has started. The options and their meanings are exactly
the same as for full_backup, except the -a option, see below. The total
backup counter is not increased.
-a Differential mode. The timestamp storing the time of the last
backup is not modified.
-E Use not only the modification time comparing the timestamps to
select filesystem entries for backup, but also the inode change
-H If this flag is set, all backups with a lower level since the
last full backup are removed from the indexes and the respective
tapes freed, if there is no other backup data on them. In
differential mode (-a) a previous differential backup is also
removed and the tapes freed, if possible
The backup level. All files modified since the most recent
backup with a level equal or higher are saved. The higher this
number, the more files are redundantly saved again. <level> can
be an arbitrary number from 0 up to 2147483646 (== MAXINT - 1).
Default: 0. A full backup has an implicit backup level of
2147483647 (== MAXINT)
