corrupt data after a tape merge

[igolo]

When I merge a tape to the database and do a restore from that tape the restored data is corrupt. I've tried this on several month end tapes (6). If the tape is already in the database the restored data is clean.

Example: data backed up in August is not in the database. After merging the August tape into the database I do a restore from that tape but the data is corrupt.

December's tape is already in the database and data restored from that tape has not corruption.

Has anyone encountered this problem?

Any help with this is greatly appreciated.

1) corruption in the database
or
2) corruption in the cat files used for the merge

to test #2 try disabling the catalong merge, the merge will then be very very slow but at least you will know if it is related to the catalog merge or not

Open regidt32.exe
Go to HKEY_LOCAL_MACHINE on Local Machine
Open it to
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\ARCserveIT\Base\Task
Highlight Task and select Edit Add Key from the menue bar.
Key Name: Merge
Class: <leave blank>
Hightlight Merge and select Edit Add Value
Value Name: DonotUseCatalogMerge
Data Type: REG_DWORD
click OK
Data: 1 *// 1 = Enabled, 0 = Disabled

the path may be differeent depending on your version

Thanks for the response, but a three hour call with CA help solve the problem. Apparently if you do a backup using the backup agent you must do the restore using the backup agent or you'll get corrupt data.
