I have 2 external drives. I would like to rotate the drives each week, so one week, I want to backup to Drive-A, next week to Drive-B and then next week back on Drive-A etc.

I see that Win 2008R2/2012 has an option called "Back up to a hard disk that is dedicated for backups", but I can't figure out how to add a second or third drive later - it seems like I have to attach all drives to the server, select the two (or more drives) when configuring the backup job, unplug so there's only one backup drive left and then I'm ready to backup. Only question is, how do I add a third drive later?

You can add additional drives after the fact by using Wbadmin from the command-line.

Wbadmin ENABLE BACKUP -addtarget:{DiskID}

The AddTarget parameter takes a disk ID as an argument, which can be retrieved by running Wbadmin GET DISKS.

Thanks! You know if using "Back up to a hard disk that is dedicated for backups" .. is just set and forget? Like do I have to erase disks or will Windows just delete old backups to make place for new backups? Thanks. – MojoDK Jan 27 '13 at 17:57
Backup is never set and forget. :) If the drives fill up (etc.) it will tell you (Event Logs), but you have to be watching for it. You can setup email alerts for various results as well:…,…,… – Ƭᴇcʜιᴇ007 Jan 27 '13 at 18:14
Thanks for helping me out :) ... Will Windows overwarite disks when it's full or will it log it and I'll have to reformat it every week? thx! – MojoDK Jan 27 '13 at 21:01
Nope, it should clean up after itself. Info here – Ƭᴇcʜιᴇ007 Jan 27 '13 at 21:04
