I have two questions for you:
1) any owners of HP SureStore DLT vs80 unit here ? If yes, what kind
of performance do you have with amrecover. I did a recover this
morning, it took 67 minutes to recover a single 2 bytes file. The
backup take 7 minutes so are this unit is really that slow for reading ?
I don't have a such a drive, but I should be much faster.
The 7 minutes, is that the dump time (to disk) or the time to write
to image to tape?
Time to write to tape
How large was the image? How fast is the tape for writing (see amanda
reports)? What filenumber was it on tape?
Avg Dump Rate (k/s) 1697.2 -- 1697.2
Avg Tp Write Rate (k/s) 1690.9 -- 1690.9
Is the client a different machine (look for network problems)?
Yes, but same subnet. No, we didn't have network problems. The tape
was busy all the time.
Did you specify "amrecover_do_fsf true" (should be much faster if the
image is near the end of tape).
I will try that.
