Backup failing

[Former Member]

We had a problem where there were server corrupted tables and indexes. We rebuilt the problem tables and indexes but the backup is still failing with the following error:

Hi there,

if you really did "rebuild the problem tables and indexes", then the reason for the failing backup is that the pages are still on the to-be-backed-up list.

In order to fix this, you should run a "CHECK DATA WITH UPDATE" in ADMIN mode.

But please make sure to have a current release of MaxDB in place here, since there had been some bugs with CHECK DATA.

Besides that, I highly recommend that you digg out the last backup that was done without error and all the log backups created since then.

regards,

Lars
