Home -> Community -> Mailing Lists -> Oracle-L -> How fast are your tape backups?
Hello list. I have a brand new database that is around 200 GB in size. Our tape backup solution which was supplied by the hosting company is only giving me bewteen 6 and 7 MB per second . A full cold backup can take 8 to 10 hours at this rate.
I looked at the specs for the tape library they sold us and it says 15MB/sec or up to 30 MB/sec compressed. What gives? The storage is SCSI 3 and also some Fibre channel so I don't think the drives are the bottleneck.
What kind of numbers are other people getting?
The system
NT 4
4GB RAM
400 GB storage (mix of SCSI 3 and fibre)
Oracle 8.1.6.3.0
~ 200 GB in Oracle data files
Tivoli Storage Manager
IBM robotic tape library (via fibre)
