I have a level 3 (weekly) ufsdump on a DLT 4700 that is only 239MB in total for the 3 weeks that the tape is loaded. On the 4th week, I remove the tape and insert another tape to do a level 0 (monthly) dump.

Question is: What is the command to append more level 3 dumps if I reinsert the level 3 tape?

Ideally, I would like to use the same command for the level 0 ufsdump.

The level 3 command is this: ufsdump 3uf myserver:/dev/rmt/5/mn

Thanks

If you want to put more dumps on the tape, you would have to use the mt command to go to the end of the last dump (or it would write over the ones you already put on there). See the man page for mt. Use the tape device that includes the 'n' (for no-rewind) and do a mt -f /dev/rmt/yourdevice'n' (such as /dev/rmt/5n) fsf 3 (where 3 is the number of to skip forward).

you should also think about the number...
theses numbers are only (exept 0) logical numbers for the administrator.
if you take your level 0 backup the whole system is backuped....
if you take your level 3 backup the changes will be saved, so if you backup a new level 3 the changes since level 0 will be saved again BUT if you would take level 4 the changes since the level 3 backup will be changed

ufsdump 0vuf /dev/rmt/0 --> whole backup
mt fsf 1 --> forward one tapestamp
ufsdump 3vuf /dev/rmt/0n --> backup changes since 0 to unrewind tape
mt fsf 2 --> forward two tapestamps
ufsdump 5vuf /dev/rmt/0n --> backup changes since 3 ....
...
..
.
ufsdump 4vuf /dev/rmt/0n --> backup changes since 3 but the 5 will be ignored and changes will also be stored....

with the -u option the system updates you /etc/dumpdates to manage the dump-levels

Thanks for the tips!

I'll try it for this coming weekend and let you know the results.
