I'm a little new to this, so sorry if this is repeat. I looked around but couldn't find what I was looking for.
I want to setup my backup to rotate between two external USB drives. I know I have to connect both of them at the same time for the initial setup. But my question comes when I start rotating the disks nightly, or weekly or whatever the rotation will be.
Situation: Disk A is plugged in on day 1, does full backup (I'm assuming). Disk B is plugged in on day 2, does full backup? Assuming yes, when I plug disk A back in on day 3, will it do a full backup again, or does it do an incremental backup?
Then, once I plug back in Disk B on day 4 or 5 or whenever I plug it back in and the backup runs (disk A unplugged), will it backup everything since the last time the backup was ran for Disk B (so 2 or 3 days worth of data) or will it only put information onto the drive since the last backup ran in general (the backup ran the night before for Disk A)?
Again, sorry if this is a basic question. Trying to help out a friend and don't have a ton of experience yet with 2012.
Thanks in advance!
