I tend to use a few strategies. Typical stuff in /home, /etc: duplicity daily backups to S3. It is small, and safe. Oh, and it is all on RAID too, which reduces the risk of needing to actually restore it (RAID is primarily about downtime, not backup). Encryption keys are burned to multiple CDs and stored in multiple safe places. Photos and other valuable media: Also gets the duplicity S3 treatment, but after every few GB I do a one-time upload to Glacier and then remove it from my daily backups. This stuff is write-once, so backing it up daily is overkill. When S3 was more expensive I would burn two copies to DVD and store offsite, but that became a PITA and Amazon is a lot cheaper now. If I ever need to restore it it is unlikely I'd need it all at once, so I can do so slowly and not get killed by fees. MythTV recordings, random video from internet, etc: btrfs raid plus a second daily rsync to ext4 (still local). The rsync is only because I'm still in playing-around mode with btrfs. Once I trust it fully I'll drop it and just rely on the RAID. I'd be annoyed if I lost all this stuff, but only for a week or two. Trying to properly back up multiple TB of media is just way too expensive and this stuff just isn't valuable enough to care about. I structure my filesystem around my backup strategy. All the stuff I really care about is in /home. Stuff I don't care so much about goes outside of /home and is symlinked back in where necessary. So, I don't need to play around with too many exclusion rules. -- Rich
