I just got this email1 from a user of my home server:
I have need of your rinky dinky back up system.
There is a file in My_Documents\\Correspondence called "XXXXXX" which I have overwritten somehow in error. Can you get the orginal back? I created it last week (Monday I think) and have not updated it since, except to overwrite it today!!
Well it turns out I can:
# /home/cjg/bin/sh/zfs_versions 'XXXXXX.odt' /home/user/.zfs/snapshot/day_2007-08-27-01:01/My_Documents/Correspondence/XXXXXX.odt /home/user/.zfs/snapshot/hour_2007-09-03-12:00/My_Documents/Correspondence/XXXXXX.odt /home/user/.zfs/snapshot/minute_2007-09-03-12:30/My_Documents/Correspondence/XXXXXX.odt /home/user/.zfs/snapshot/minute_2007-09-03-12:50/My_Documents/Correspondence/XXXXXX.odt /home/user/.zfs/snapshot/hour_2007-09-03-13:00/My_Documents/Correspondence/XXXXXX.odt #
