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

Unlike a number of modern file systems, Ext3 does not have native support for snapshots - the ability to quickly capture the state of the filesystem at arbitrary times, instead relying on less space-efficient volume level snapshots provided by the Linux LVM. The Next3 file system is a modified version of Ext3 which offers snapshots support, yet retains compatibility to the EXT3 on-disk format
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.
