Hello,
A client sent me DB backup files from SQLServer 2005 and I'm trying to restore them on SQLServer 2012.
My counterpart has confirmed that the files can successfully be restored to SQLServer 2005, so the files are not corrupted.
However when I try to restore them on SQLServer 2012, some can be restored successfully, but two of the files result in Message 3242 (not a valid Microsoft Tape Format backup set).
I have tried changing the compatibility level of the target DB to SQLServer 2005(90), but without luck.
Other factors that may be affecting are;
1) Difference in versions: The online MSDN document states that you can restore a DB from a database backup from 2005 to 2012, but I'm wondering if there are any restrictions.
2) File sizes are large: The failing backup files are 30GB and 100GB, whereas the files that I could restore successfully are 12GB at the largest.
Has anyone come across such an issue?
I'd appreciate any insight as to what I can do to resolve this issue.
Errors that I'm seeing:
RESTORE DATABASE xxxx FROM DISK=yyyy WITH FILE=1, RECOVERY, REPLACE
results in Message 3183: RESTORE detected an error on page (0:0)
RESTORE DATABASE xxxx FROM DISK=yyyy WITH FILE=1, CONTINUE_AFTER_ERROR, RECOVERY, REPLACE
results in Message 3242: The file on device yyyy is not a valid Microsoft Tape Format backup set
