NAME

incr_backup - run an incremental backup with the afbackup package.  

SYNOPSIS

incr_backup <options ... See: full_backup> [ -EH ] [ -Q <backup-level> ]  

DESCIPTION

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 time (ctime)
-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
-Q <backup-level>
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)
