Is this at all possible.....backing up of nfs mounts

[Kanulondon]

I haven't tried this yet but I have a HPUX workstation with a DDS2 tape drive...

On windows pc I have linux too and all the windows files are under /mnt

could I make /mnt an nfs mount and backup files on my pc onto DDS tape?

It's possible but would be slow.

Much easier to do with CiFS (Samba).

Install both GNU tar and CiFS client (both free) and use smbtar to backup your PC shares to dds in a single command without the serious slowdown of NFS

Enjoy, have FUN! H.Merijn

If you just wants to backup files to the remote tape drive, you can do 'fbackup':

# man fbackup
# remsh system2 fbackup -f system1:/dev/rmt/0m -i -v
# fbackup -f system2:/dev/rmt/0m -i -v -O

Yes, this is possible. The 'slowness' issues mentioned earlier are true, but 'slow' is relative. The disk on the PC is slow, the network may be slow (10baseT ~= 1MB/s, tops), or may be OK (100baseT ~= 9-10MB/s max), your workstation may be slow (712 or C110), or may be faster/newer, NFS is OK but not terribly efficient, but the DDS2 DAT drive is, well, slow.

DDS2 DAT4/8 drives do about .5MB/s native, 1MB/s with 2:1 compression, your mileage will vary. Given that this is your backup media, the relative slowness of everything else in your environment will probably be a non-issue. Your drive will be the bottleneck, so, go for it.

The only thing in your setup that may be more of a bottleneck than your DDS2 DAT drive would be your network, if it is only 10baseT. In that case, if you have data that compresses well, your network speed may be an issue. But with your expectations properly set, and speed not being an issue, there is no reason why this shouldn't work. Go for it.

Hi,

I have understood that from your box you need backup a NFS that be inside, for this condition with fbackup command you must indicate -n option, pls chck "man fbackup" for detailed info.
