Hi,
I have a HP SureStore DAT24 connected on a Solaris 8 box, i am trying to backup using ufsdump. Its working fine. But when i try to append some more stuff to the same tape its doesn't work, i am using the below command for backup,
# ufsdump 0bf 64k /dev/rmt/0cn /export/home/raj
Also any ideas about any freeware backup software's available.
Regards,
Rajendra Rait.
Gah - I <b>did</b> this before I threw away using ufsdump as being not worth the hassle.
You are correctly using the norewind device so as long as you are adding to the tape straight after the ufsdump you should be alright - I am not sure what would happen if you ejected the tape after the ufsdump.
Hello Rajendra,
<i># ufsdump 0bf 64k /dev/rmt/0cn /export/home/raj</i>

It appears to me that you rewind/reposition the tape after the above command. If the tape is repostioned in the meantime (eg. rewind or just reading the tape header) it doesn't append.
# mt rew
# ufsdump 0bf 64k /dev/rmt/0cn /export/home/raj
# ufsdump 0bf 64k /dev/rmt/0cn /export/home/ana
The third command appends to the tape, it doesn't overwrite the first session/set.
Rewind the tape <b>before</b> doing the backup and use consecutive commands (ufsdump) to backup the filessystems/directories.

I followed the following steps,
# mt rew
# ufsdump 0bf 64k /dev/rmt/0cn /export/home/raj
#ufsdump 0bf 64k /dev/rmt/0cn /export/home/test
after that i got to the ufsrestore prompt by issuing this command,
# ufsrestore ivf /dev/rmt/0
ufsrestore > ls
.:
2 *./2 *../43448 export/
ufsrestore > cd export
ufsrestore > ls
./export:
43448 ./ 2 *../11009 home/
ufsrestore > cd home
ufsrestore > ls
./export/home:
11009 ./43448 ../203 raj/
the thing is that i should get the test folder also in the above list, but that doesn't work. Is there anything that i am doing wrong.

Please bear in mind that all my knowledge of ufsdmp and ufsrestore is quite old and self-taught/discovered ...
I <b>thought</b> ufsdump would backup the whole of a ufs partition, but I could be wrong, thus with your two commands it would seem that each ufsdump is backing up only <b>part</b> of the file system (an assumption that the file system /export/home contains both raj and test).
If my assumption is correct then you need to tell ufsrestore to skip to the second ufsdump file on the tape - I seem to recall the -s parameter doing this (all this can be found from the man page for ufsrestore).
A far, far easier way of doing this would be to back up ALL of /export/home in one fell swoop using <b>ufsdump 0bf 64k /dev/rmt/0c /export/home</b>
Hello Rajendra,
I was wrong. You didn't reposition the tape in the meantime, <b>but</b> as SimonM noted you must position the tape to the next session.
Please take the time to review the man pages for <b>ufsdump</b>, <b>ufsrestore</b> and <b>mt</b>.
You are looking for <b>mt fsf 1</b>.
Michael
