Oh, I didn't comment on this part, so sorry for the double reply. |

If you need backups that span multiple disks your options are very |
12 |
limited unfortunately. Most linux backup software might output |
13 |
multiple files but it dumps them all in one place and much of it |
14 |
assumes that all the files are in one place for restoration. Here are |
15 |
the options I've found: |
16 |
|
17 |
1. You can use lvm/zfs/btrfs/whatever to combine multiple disks to |
18 |
make them look like one disk. This is a workaround, and obviously |
19 |
you're limited to however many disks you can physically mount at one |
20 |
time. |
21 |
|
22 |
2. You can use bacula, which does support changing media, since it was |
23 |
designed for tape, but unlike tar it can output to a directory. |
24 |
However, this is not very well-supported and it can be a pain. This |
25 |
is what I'm doing for large-scale backups. I basically treat a hard |
26 |
drive like a giant tape. It is fussy to set up and use, and bacula |
27 |
itself is VERY fussy to use. Oh, and make sure you REALLY understand |
28 |
it and do some restoration tests because otherwise you could paint |
29 |
yourself into a corner. I always backup my database, and I have the |
30 |
bacula software itself running in a container and after every backup I |
31 |
just create a tarball of the whole container and stick that on the |
32 |
backup disk (it isn't big, and that solves the bootstrapping problem). |
33 |
Don't ever use bacula to back up itself - it is terrible for that. |
34 |
|
35 |
3. Obviously if you have a scratch disk big enough to hold everything |
36 |
temporarily that also works. You can do your backup, then copy it off |
37 |
to other drives however you want. |
