is ther any permissions required to be set.

THanks in advance.

Use SAM:

Backup and Recovery -> Interactive Backup and Recovery -> Actions -> Use Remote Backup Device -> Back Up Files Interactively...

You can use fbackup to write to a remote device by specifying the tape device as apple:/dev/rmt/0mn

or

You can use for example tar (or cpio etc) to a remote tape drive with:-

micky# tar cvf - / | rexec apple "dd of=/dev/rmt/0mn"

This will tar to stdio, which will be passed to dd via the pipe, which will write it to tape.

You may need to experiment with the bs= parameter of dd to get optimum performance.

Hi Govind,

I think it's something like this:

fbackup -f :/dev/rmt/0m ...

thanks simon and antu,

thanks

Govind,

If you want to restore data you should know what format backup is taken. If backup has taken using fbackup you can restore it using
#frecover -f apple:/dev/rmt/1m ..

Sunil says how to restore the fbackup

To restore the tar (as I backup up above): -

micky# rexec apple "dd if=/dev/rmt/0mn" | tar xvf -

[Eric Antunes]

To recover try this:

frecover -f MICKY:/dev/rmt/0m -v

Add -I /var/tmp/index_test if you used an index when doing the fbackup

[Eric Antunes]

Yes, Sunill has already posted the frecover command.

When I wrote "frecover -f MICKY:/dev/rmt/0m -v", I wanted to post:

frecover -f Apple:/dev/rmt/0m -v (Apple is the server with DLT)

NOTE: all of the remote tape activity is specific to HP-UX. Both apple and micky must be HP-UX. fbackup is meaningless on non-HP-UX computers. If the DLT is on a PC or on a Linux or Sun box, you'll have to use remote shell pipes and run tar. Warning: tar won't handle large files. Also note that most networks are far too slow to keep a modern DLT running properly. Excessive tape repositions will occur with LAN speeds less than GigE (ie, 100Mbit or less). If this is part of a production backup strategy, I would get a local tape drive as soon as possible. It is possible to ruin a DLT (or Ultrium or AIT, etc) drive in less than a year with slow backup speeds.
