Option 2 of the RescueBRU main menu (Do a backup) allows backups to
be performed. It first attempts to mount the particular backup media
you selected, and then asks you to choose an image name from a list
or supply a new name for the backup. This name will become the name
of the directory on the NFS server or USB drive where the backup
images are stored. It should be short, but descriptive. It cannot
contain spaces or special characters. For example, "SJ#4 Display PC
3 (Pilot/ WSO UFCs)" would not be accepted. A better alternative
would be "sj4disppc3". After you supply a name for the backup, a
directory is created on the backup media to store the images.
RescueBRU then probes the hard drives and generates a list of drives
and their partitions. Because you may not always want to back up all
partitions of all drives, RescueBRU prompts you whether or not to
back up each MBR and each partition. Select what you want with the
spacebar. After choosing MBRs and partitions, you will be prompted
to confirm the options. Once you have selected Ok and confirmed, the
master boot records and the partitions you chose are backed up.
An important note about the dd method:
When selecting drives and partitions to be backed up using this
method, be aware that dd backs up the entire drive (/dev/sda
for example) not just the MBR like the other methods. This means
that if you select a drive (/dev/sda) you should probably not select
any of the drive's partitions, since the data contained on them is
already in the backup of the drive itself. Selecting the drive and
its partitions will make the backup take a long, long time and be
ludicrously huge. However, RescueBRU never assumes it knows more
than you and will happily oblige if you tell it to.
When the backup is complete, the backup media is unmounted and you
are returned to the main menu. From here you can perform other
operations or exit RescueBRU.
