Re: [rdiff-backup-users] rdiff-backup and rotated external drives

There is no way for rdiff-backup to know what changed if you swap the drives, so it would be missing out on a week of changes. A cheap way around this (and what I do) is I have rdiff-backup backup to an external drive, and then I clone that external drive to another one using rsync, and the second external drive becomes the off-site backup.

Looking at rdiff-backup as an Ubuntu Server solution. It looks great, but I can't find any documentation on using multiple external hard drives and how it will handle them being rotated off-site. I'd like to have at least two externals that will rotate weekly. Does rdiff work with this setup?  If so, can I keep the two drives in sync? In other words, if Drive1 is attached this week and backs up incrementally daily then Friday I rotate in Drive2 through next Friday, will Drive2 somehow include all the incremental changes--and therefore deleted/changed files--that happened in the week it was off-site? Or, will I only have every-other week's changes on one drive?
