I tend to use a few strategies. |
24 |
|
25 |
Typical stuff in /home, /etc: duplicity daily backups to S3. It is |
26 |
small, and safe. Oh, and it is all on RAID too, which reduces the |
27 |
risk of needing to actually restore it (RAID is primarily about |
28 |
downtime, not backup). Encryption keys are burned to multiple CDs and |
29 |
stored in multiple safe places. |
30 |
|
31 |
Photos and other valuable media: Also gets the duplicity S3 |
32 |
treatment, but after every few GB I do a one-time upload to Glacier |
33 |
and then remove it from my daily backups. This stuff is write-once, |
34 |
so backing it up daily is overkill. When S3 was more expensive I |
35 |
would burn two copies to DVD and store offsite, but that became a PITA |
36 |
and Amazon is a lot cheaper now. If I ever need to restore it it is |
37 |
unlikely I'd need it all at once, so I can do so slowly and not get |
38 |
killed by fees. |
39 |
|
40 |
MythTV recordings, random video from internet, etc: btrfs raid plus a |
41 |
second daily rsync to ext4 (still local). The rsync is only because |
42 |
I'm still in playing-around mode with btrfs. Once I trust it fully |
43 |
I'll drop it and just rely on the RAID. I'd be annoyed if I lost all |
44 |
this stuff, but only for a week or two. Trying to properly back up |
45 |
multiple TB of media is just way too expensive and this stuff just |
46 |
isn't valuable enough to care about. |
47 |
|
48 |
I structure my filesystem around my backup strategy. All the stuff I |
49 |
really care about is in /home. Stuff I don't care so much about goes |
50 |
outside of /home and is symlinked back in where necessary. So, I |
51 |
don't need to play around with too many exclusion rules. |
