Well ext2 just spits out errors without oopsing. I'm not sure about XFS or JFS.

Whatever fs you prefer. That's why there's a choice !

No. Once the snapshot is full then it can't be valid because there may be
blocks written to the original device that the snapshot can't backup. The only
way aoud this is to make your snapshots large enough to hold all the data that
is going to change on the original device during the backup.
