Question:
When restoring from snapshot, is there a method which will not recreate data in the real data area.
Example:
Random files are removed throughout the filer. We decide to backtrack to Mondays snapshot. We plan to copy everything out of snapshot back to the real data area.
Solution 1: use 'find' and 'cpio' and transfer all the data back. this would appear to require 2x current capacity of the filer to replicate all data out of snapshot. if you're using >50%, this method would fail.
Solution 2: use 'find' and 'diff' and 'cpio' to enhance solution 1 with a check. Now only files which differ from the snapshot will be replaced.
Solution 3: dump the snapshot to tape, and then restore from tape after removing existing snapshots.
Solution 4: boot from floppy, use prev_cp and wack? Has anyone had any experience with 'prev_cp' and 'wack'? We're leaning at #4. Any comments would greatly be appreciated!
