dumpdates - data base of file system dump times
/etc/dumpdates
The dump command (see na_dump(1)) uses /etc/dumpdates to keep track of which subtrees have been dumped and when. Each line in dumpdates contains the subtree dumped, the dump level, and the creation date of the snapshot used by dump. There is only one entry per subtree at a given dump level. dumpdates may be edited to change any of the fields, if necessary.
This shows the dumpdate file for a system on which /home and /export are backed up using dump.
/home 0 Tue Nov 2 10:56:27 1993 /export 0 Tue Nov 2 13:51:17 1993 /export 1 Tue Nov 5 18:31:17 1993 /home 1 Tue Nov 5 18:45:27 1993
