Very long Netware restore
2003-09-23 14:08:43
We recently did a full restore of a Netware server. Basically, we're
interested if the restore time sounds reasonable - it doesn't to us.
The server that was restored is actually at a remote site from the
TSM server location, but the restore was done at the TSM site, then,
driven to the remote site for installation.
The restore specs read like this:
Compression: Files compressed using TSM client compression
Size: 240gb
Files: 938,617
Restore Time: 50 hours
Throughput: around 1.3mb/s average speed (240gb/50hr)
Network: 100MB/fdx, local to TSM server
(admins checked for duplex mismatch)
Tape Drives: IBM 3590
Netware Server
Version: NW5.1 SP3
Dell 2650
1 - 2ghz xeon processor
2gb memory
513mb cache on processor
This just doesn't sound right. After this was all done, we created a
backupset to see
just how fast TSM could access the servers files.
Backupset Creation Time: 11 hours
From Tape Drive: IBM 3590
To Tape Drive: IBM 3590
So . . . . the bottleneck doesn't appear to be the TSM server.
Any thoughts as to why our restore took 50 hours??? The obvious answer is
that the files had to be uncompressed on the client, but I would have
thought
a 2ghz processor would be able to uncompress much more than a 1.3mb/s data
stream.
Thanks
Rick
