I tried LVM a few years back and "burnt my fingers" as it were - I found it slow and unstable, but times are changing, progress being made, etc. so does anyone have any input on it's current stability and usability?
Basically, I'm running out of steam on some backup servers I have - trying to copy several TB of data using cp -al, then rsyncing on top of it (and then copying the copy, etc. to give me 30 days of backups) has been working well for some time, but the data-set is increasing all the time, and the cp -al is currently taking 4-5 hours, so snapshotting via LVM is looking like it's something I think I ought to be looking into again.
The current data-set is 5TB, and having 150TB of storage isn't an option right now... Essentially I need to be able to keep 30 cycles (days) of snapshots on a server that is not a live server (ie. it's a huge disk array, in a secure bunker backing up several remote servers every day, and dumping the occasional snapshot to tape for archive. Data comes into the server via a 100Mb line & rsync from the remote servers).
So is LVM(2) up to this task these days, or should I really be looking at something else?
