SQL Agent Transaction Log backups
What are people doing for transaction log backups? We have an environment with close to 1500 servers (mix of physical and virtual,) have jobs running 24x7, and have recently started using the SQL Agent instead of the dump and scoop method. Our DBA's insist on running a transaction log backup on all SQL databases every 10 minutes. Previously they dumped to a CIFS share that was scooped weekly. Now with converting to the agent, we've added close to 600 jobs per hour with this configuration, and it seems to be causing some additional scheduling issues. It seems excessive to me, and array based snapshots are not an option. Any tips/tricks/suggestions that could be shared regarding this would be beneficial.
I tried to find a SQL Agent best practice guide, but all I kept stumbling across was an HP version.
15000 jobs per day - not great - and not great for the catalog and its file system i guess!
My largest clients runs about 7000 jobs per day every day and that one copes but has been heavily tuned to cope with running out of desktop heap etc.
It may cause you issues but you will only know if you try - when desktop heap runs out it is easy to tell as it just stopps working with no event logs and nothing logged anywhere - it just dies! (Sometimes you are luck with a w2k error in the event logs)
The trouble is with WIndows is that you can have 128GB RAM but desktop heap is still tiny!!
I would be inclined to ask the SQL Admins if they really need it - or maybe a full backup nightly and let them dump to their own disk every 15 minutes and backup those dumps every hour or two!
