I have had to restore ~52GB of data several times now, and it generally takes around 6 hours over Gigabit ethernet. It's around 800,000 files, most of them very small. Besides the small files, it also has the problem of being a high-turnover group of files. So the restore is spread out over a lot of tapes. I would think (hope) that this represents pretty close to a worst-case scenario.

Today I used the client TSM gui and requested an estimate of file sizes and times to restore this intel drive. The gui came back with the estimate of 125 hours to restore 260GB of data contained in 974008 objects. How good are these estimates and how can I get this time down from 0.0346GB/minute to 1.0GB/minute (260 minutes to restore 260GB of data)? The network is 100Mb/sec, so that's 450MB/hour. That's seems to be 591.8MB/hour. The reports do not show that compression is turned on for any (not this) clients. How does this work out?
