Thanks Howard, The hardware guy's gone for the day, so I'll get his details tomorrow. The DB is about 150 Gb with about 450m files. Log is 12 Gb. We have few problems handling 1-1.5 Tb a night. My worry is the lag in the DB backups.

What kind of hardware? Do you have caching turned on at the filespace level if its JFS2? (needs to be off I found out). Are they all on a single disk (db volumes and log volumes) or do you have them spread out, and are they mirrored on different disks? How much RAM and How many Procs? I have my db and logs local but I have them mirrored, its only about 70 GB, and I have them spread out.
