Restore from increment media

Jump to solution
After a disk crash + subsequent restore we learned the hard way that our increment chain seems to be incomplete 😞

What we SHOULD have (and what we DO have)
- full backup SAT (already restored OK)
- increment 1 SUN (DB pointing to wrong full-BU)
- increment 2 MON (missing)
- increment 3 TUE (missing)
- increment 4 WED (seems OK on tape + DB)
- increment 5 THU (seems OK on tape + DB)

The missing increments are a problem, but most of the files on these will have changed in the meantime + thus be contained in increments WED+THU.

We are looking for a way to restore these last two increments on top of the full backup...
...but DP 5.5 won't do it:

We tried
- File System Restore
- Session Restore
- List from Media Restore (Tapes are known)

We got
- Message 12:1254 'Full Restore Chain is broken or missing media needed for the restore'

Well - we knew that before ;-(

Does anyone have experienced a similar problem + may know a solution?

Would there be any way to restore from an increment media directly without having DP nagging about broken chains?

Thanks for your help + all the best

Hi,
To restore a incremental session only, you must use the comand line. Don't know why .
Below is an example from the man page. The "-full" option will rwstore the complete backup chain. If "-full" is omitted, the incremental session only is restored (assuming that "1994/07/12-2" is an incremental session.

omnir -filesystem bb:/ -full -session 1994/07/12-2 -tree /ac

Omnir is a very complex command and you should read the man pages before trying to use it.

Hello Leif,

you are perfectly correct. I went through the omnir man page + assembled a command (w/o the -full option 😉 that indeed restored the increment without any complaints.

I found the -merge option quite handy - the restore will not overwrite any file with a newer timestamp on the server.

Again - thanks for your help

take care
