psusifyi, if you are using lvm I have uploaded a much newer version of the lvm tools to my ppa which allow you to take a snapshot, upgrade, and if things go tits up, revert to the snapshot in a snap... handy thing to have when running the development release14:48

* cwillu_at_work pokes BUGabundo with a stick21:55
BUGabundodding my disk21:55
cwillu_at_workBUGabundo, btrfs-image is just a debuging image, you know that right?21:55
cwillu_at_workdebugging, rather21:55
BUGabundoso I can go a on confernce and leave a backup21:55
BUGabundowith btrfs-image21:55
cwillu_at_worki.e., metadata, with zero'd out file data21:56
BUGabundono I did NOT know that21:56
BUGabundoteach me oh big ONE21:56
cwillu_at_workwhat are you trying to do again?21:56
BUGabundodding21:56
BUGabundodisk image21:56
cwillu_at_workah.21:56
BUGabundobackup21:56
cwillu_at_workI suggest rsync :p21:56
BUGabundoLOL21:56
BUGabundowant a compact volume, with lol CPU overhead21:56
BUGabundosoooo21:57
BUGabundomake a snapshot and rsync that?21:57
cwillu_at_workBUGabundo, i.e., you want to leave behind a backup?21:57
BUGabundoyah21:57
cwillu_at_workor do you just want a snapshot, but on the same media21:57
cwillu_at_workokay21:57
BUGabundoincase robbery, damange, etc21:57
cwillu_at_workdo you have any subvolumes and/or snapshots?21:57
BUGabundono, external 2TB drive over e-sata21:57
BUGabundobought it JUST for disks backup21:58
cwillu_at_workI meant on the existing btrfs21:58
BUGabundono subvolumes or snapshots here21:58
BUGabundoonly /21:58
cwillu_at_workokay, yeah, just rsync21:58
BUGabundoand /boot on ext221:58
cwillu_at_worksnapshot if you want it to be consistent without shutting down postgres or whatever :p21:59
BUGabundocan't I just snapshot to the external disk?21:59
BUGabundoits on btrfs too LOL21:59
cwillu_at_workBUGabundo, there are tricks that could be implemented, but they're not implemented yet :p21:59
BUGabundok k21:59
BUGabundoso local snapshot then rsync that21:59
BUGabundolet me try21:59
cwillu_at_workBUGabundo, if you snapshot the backup media as well, and use --inplace for rsync, you get semi-efficient incremental backups22:00
cwillu_at_worki.e., rdiff on steroids22:00
BUGabundocoolio22:00
BUGabundo/var/snapshots$ sudo btrfs subvolume snapshot 20101108 ?22:01
BUGabundooops22:01
BUGabundomisses the volume22:01
cwillu_at_workBUGabundo, I believe so, although you should get in the habit of using absolute paths with snapshots/subvolumes22:01
BUGabundo/var/snapshots$ sudo btrfs subvolume snapshot / 2010110822:01
BUGabundok k22:01
BUGabundo$ sudo btrfs subvolume snapshot / /var/snapshots/2010110822:01
BUGabundoCreate a snapshot of '/' in '/var/snapshots/20101108'22:03
BUGabundoyay22:03
cwillu_at_workBUGabundo, now, be aware that deleting snapshots is asynchronous;  the command returns immediately, but the space is reclaimed over time22:04
BUGabundoI won't delete it *now*22:04
cwillu_at_workthere's a syscall in the works to block on completion, but it's not there yet22:04
BUGabundojust rsync it to external drive22:04
BUGabundoI know, you told me that once already22:04
* cwillu_at_work repeats himself22:04
cwillu_at_workBUGabundo, also, be aware that deleting snapshots is asynchronous;  the command returns immediately, but the space is reclaimed over time22:04
BUGabundoI have lousy memory22:04
BUGabundobut I do learn a few things from time to time22:04

BUGabundoeven worse... its backuping my backups LOL22:11
cwillu_at_workBUGabundo, could be fun to disable checksumming while it copies, but if you don't, check dmesg after to see if you have any corrupted files22:12
