Increasing Restore Speed

Hi:

I'm running amanda 2.4.4p3 on a solaris 9 Ultra2 and backing up severalremote linux and solaris hosts to an HP Tape Library device. Everythingin regards to the backups seems to be working ok.

In my current situation I have to restore 21Gb of data within a limitedtimeframe to a remote host on the same network segment. The last trialthat I ran I got at max 2.5Mbps restore speed which ended up being closeto 24 hours to restore completely.

All devices are communicating at 100 full duplex with no errors onswitches or hosts. With that I'm left thinking that the limiting factoris most likely getting the data off of the tape. I do know that amandacan backup data to disk like a mofo, I routinely get the 60mbps which Iset as my max when backing up to holding disk.

That begs the question of if I can get 60mbps backing up to disk, can Irestore the file from tape to disk locally and then use amrecover on theremote host to read directly from the disk instead of the tape?


can I do something like

/usr/local/sbin/amrestore -f1 /dev/rmt/1mn hostname diskname 20050819

On the local system

On the remote system and I use amrecover like

/usr/local/sbin/amrecover -C hostname -s index.server -t tape.server -drestored-filename


Any ideas, hints, tips, tricks appreciated.

Thanks,
