cbackup(ADM)
cbackup --
perform unattended incremental backup
Syntax
/usr/lib/sysadmin/cbackup level len
device filesystem
Description
cbackup allows unattended incremental backups to be made by calling
it from the crontab file (see
crontab(C)).
cbackup takes four arguments:
level-
The increment level of the backup to be made.
len-
The capacity in kilobytes of the media to be used in the backup. Note that only one volume can be used since this is an unattended backup.
device-
The name of the raw device to make the backup on.
filesystem-
The filesystem to be backed up. Since cbackup uses
cpio(C),
the filesystem must be mounted when it is backed up.
Examples
The following entry from crontab backs up the entire root filesystem
at 2.00am every day on a 150MB cartridge tape:
0 2 * * * /usr/lib/sysadmin/cbackup 0 150000 /dev/rct0 /dev/root
Further examples may be found in
``Performing unattended backups'' in Backup and Restore
Limitations
The unattended backup must fit on one volume of the media being used.
Authorization
Only root can run cbackup.
