Does the ext3 filesystem support snapshotting? If so, is can this be done with straight partitions with no LVM?
An example of "straight partitions" would be the following:
- /dev/sda1 /boot ext3
- /dev/sda2 / ext3
- /dev/sda3 swap
I would recommend R1Soft Hot Copy for taking a point-in-time snapshot of a filesystem. Using this, you can take a clean snapshot without using LVM. It's pretty clean and should give you what you're asking for.
