This reveals a significant advantage to using LVM, if you wish to use snapshots as the target for backups. I personally prefer this, as I mentioned in another e-mail in this thread, due to getting a "crash consistent" view of the disk since it will not change while the backup is in progress. The fact that LVM snapshots happen instantly is an advantage, and also that you can perform the snapshots while the system is running. -- Randy Barlow
