ext3/4:
I excluded them because as I understand, they do not support
snapshots (only with lvm, which I do not use, and I've hreard
snapshots in lvm are not very effective, or something like that).
Next minus-point, I tried resizing of ext3/lvm once in the past
and remember it was a real pain in a**...
Any Mysql db smaller than 200GB is being backed up by a combination of
LVM/Ext3 at a large Internet company with a big purple Y. It's mildly
painful to setup, but RHEL uses LVM by default so it's just a matter of
resizing to get the partitions you need. Once that's done you can kick
off snapshots with very little effort.
Not sure where you heard it was ineffective and I'd ignore further
information from that source.
