Backup to NAS over network takes 3 times longer than to tape

[mdcr]

We have ARCSERVE 9 installed on a server with a DLT tape drive (server1), a client file server with remote agent (server2), and a new NAS server for backups (server3). When we backup local files and client files from the remote server/server2 to the DLT tape drive, the job (about 50Gb total) will take about 6 hours. When we tried to backup local files on server1 to the NAS/server3 as a test, it took over 7 hours just to backup those 10Gb of local files. Based on this test, we were guessing that the backup of the client files on server2 would take so long that it wouldn't be practical. Should ARCSERVE be installed on the NAS and just do backups between 2 servers instead of 3?

If it windows powered NAS just install the host server on the NAS box itself.

The way you are doing it at the moment means not only are you backing up over the network you are then pushing the data over another network connection again to store it on the NAS server where presumably you have configured a remote file system device.

I'd also make sure you have a dedicated Gb network for the backups.

Installed ARCSERVE on the NAS server itself and ran a backup last night; it backed up 53Gb in less than 4 hours (not over a Gb link, but 100Mb still works), so it looks like that solution worked. Thanks!
