I use rsnapshot to automatically backup a few servers to save |
| 12 |
the data onto a raid 5 disk array. I have it set to take daily and weekly |
| 13 |
snapshots of the data. |
| 14 |
|
| 15 |
As to the root partitions, I run xfs so that I can attach a USB or |
| 16 |
Firewire hard drive and do an xfs dump/restore, which copies the |
| 17 |
partition I'm after - |
| 18 |
|
| 19 |
xfsdump -l 0 - /sourcedisk | xfsrestore - /targetdisk/ |
| 20 |
|
| 21 |
The nice thing about xfsdump/xfsrestore is the partitons don't have to be |
| 22 |
the same size. The backup partition just has to be as big or bigger than |
| 23 |
the original. But I generally don't make backup partitions, just use it |
| 24 |
when swapping out hard drives. |
| 25 |
|
| 26 |
After the copy, I run xfs_check or xfs_repair to verify the new partition. |
| 27 |
|
| 28 |
As far as worrying about the root partition, I don't. Typically, I |
| 29 |
can have a functional Gentoo system back to where it's usable for |
| 30 |
it's main function in about 2 hrs. Desktop and nice things by the |
| 31 |
next day. I learned a long time ago not to worry about the operating |
| 32 |
system and just be concerned about the important things - the data. |
| 33 |
The os can always be re-installed. |
