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.
