FSD Disk to Disk to Tape

[krobert]

I am just getting ready to try to implement the Disk-Disk-Tape backup solution and have read through all the posts I can find on this subject. I have found a lot of good input, but I seem to be stuck on one aspect of the process. I was able to do the Disk-to-Disk but when I did a tape copy of my sample backup (24 MB)- it took almost 3 hours to tape copy the data. My understanding was the disk-to-disk would be a much faster way to do backups and then I could do tape copy so that I could have a copy offsite. I have a Sony AIT Autoloader (LIB-D81) that I am copying to. We have ArcServe v11.5 SP3 (Build 4405) on a Windows 2003 Server SP1. If anyone has any input on some setting(s) I may have incorrect, I would appreciate any assistance you could share. Thank you.

no idea why tapecopy would be so slow.
? is if it is a problem specific to tapecopy or any time data is written to tape.
Run a regular backup to tape to see what the throughput is.

I have no idea what possessed me to do a tapecopy. I see that in version 11.5 you can set it to automatically tape copy and purge once the backup job is complete. I completely removed everything I had configured, reconfigured, retested and all is well. I just finished the testing and it went great. On a job that took 40 minutes to backup, it only took 10 minutes to copy over to tape. Thank you.
