Solved Can restoring individual files from UFS snapshots?

Hello,

can restoring individual files from UFS snapshots?

And do the UFS snapshots save only the changes (delta) that were made or the complete file system contents all over again?

Thanks.

A snapshot is logically a readable second copy of the file system, "mounted" under the snapshot directory. To restore an individual file, just copy it from the snapshot to the live file system.

All snapshots I've ever worked with only change deltas. The actual implementations can be very different, of different performance and efficiency, and depend heavily on the internals of the file system. But the act of "making" a snapshot does not create a complete second copy. That's why it usually finishes nearly instantaneously.
