User guide

To back up the RAID-1 volume DYN2, run the following command:

acrocmd backup disk --volume=DYN2 --loc=/home/user --arc=my_archive

To back up all three hard disks with volumes, select the volumes 1-1, 1-2, 1-3, DYN1 and DYN2:

acrocmd backup disk --volume=1-1,1-2,1-3,DYN1,DYN2 --loc=/home/user --arc=my_archive

If you select Disk 3 or volumes 2-1, 2-2, 4-1 or 4-2, the program will create a raw (sector-by-sector)

backup.

4.10 Scheduling backups under Linux using the cron

service

To automate backups, you can use the cron service familiar to many UNIX users.

Example

Let’s assume that you need to back up a volume regularly. A full backup has to be created weekly,

supported by incremental backups created daily.

Use the list disks (p. 18) command to obtain the necessary volume number. For example, the

volume number is 2-1.

Create two executable files for the daily and weekly backup (for example, abr.cron) and place them

into the /etc/cron.daily and /etc/cron.weekly directories, respectively.

To initiate weekly full backups of volume 2-1, add the following line to the

/etc/cron.weekly/abr.cron file:

#!/bin/bash

acrocmd backup disk --volume=2-1 --loc=/mnt/my_archives/my_host --arc=my_archive

where /mnt/my_archives/my_host is the path to the backup location.

The second abr.cron file is needed to initiate daily incremental backups.

#!/bin/bash

acrocmd backup disk --volume=2-1 --backuptype=incremental

--loc=/mnt/my_archives/my_host --arc=my_archive

For more information, see Help of the cron service.
