Transaction Log backups failing

  • Hi,

    The error description shows that the problem is not with the transactional log backup, the error says

    BACKUP DATABASE and not BACKUP LOG.

    Please check wether transactioanl log backup is coinsding with the full database backup.If possigble try reducing the transactional log backup schedule to 1 hour.

  • Ok thanks for you reply, I think I got it fixed, I had to recreate the job and it seems to be running fine now.

  • I have exactly the same error but my transaction log backup was already an hourly backup. I have removed log backup but database is still growing at a significant raete.

  • We're having the same problem. And, we're finding that the database is growing by 3% per day (or about 20% a week), and it is two tables ... the ones that store Index Server content. We've only been trending it for the last 30 days with Idera Diagnostic Manager, but it really looks like a MOSS setting or something under the Sharepoint hood. Any ideas?

  • My system is also a sharepoint system that was growing the tlog so fast it filled the disk in about 2 days! A 20 gig tlog file was not unusual! I ended up creating a 2005 maintenance plan to back up the transaction log every hour and added to that job a cleanup task to delete files older than a day (as far as I can tell 24 hours is the earliest a file can be deleted using the maintenance plan) as a result I have 24 tlog backups. I then created another maintenance plan which backs up the database itself once in a 24 hour period (I have the database backup run between the time the tlog backup runs). What this has done has kept the space used constant with very little growth. If your problem is wild tlog file growth this approach has thus far worked for me. Hope this helps!

    Are you using MOSS or WSS? We have WSS set up in development using the Microsoft Internal Database (aka SQL Server Embedded Edition). The only backups we could do through WSS are full and differential backups. Unfortunately, the content database was using the FULL recovery model so the transaction log was not getting cleaned up. Finally figured out how to connect SSMS to MID, and set the database to use the SIMPLE recovery model, then shrunk the transaction log. Freed up 4 GB of disk space, and we haven't had space issues since.

    I'd look at your backup processes and what recover model the MOSS/WSS databases are using.

  • Change the recovery model from simple to full or full to simple - this will reset all the bitmaps.

    Then perform a full backup. Set the database to the recovery model that you want and again run a full backup.

    Hope this works for all

    FYI, this is a 3+ year old thread.

    Changing recovery models won't affect the differential bitmaps, the mechanism of full and differential backup is independent of recovery models.
