Hi,

There are so many option with you

1. tar
2. cpio
3. fbackup
4. dd

The easiest and most commonly used is tar

TO Backup use
#tar -cvf /dev/rmt/xmn ./path_to_directory

To Display contents of tape
#tar -tvf /dev/rmt/xmn

To Restore to alternate location use in that directory
#tar -xvf /dev/rmt/xmn .

man tar for deails./dev/rmt/xmn is your tape device file.

HTH,
Devender

Hi,

I recomend you to use SAM (System Adm. Manager). Just type sam:

#sam

And go to Backup and Recovery -> Interactive Backup and Recovery -> [select yout tape drive] -> Back Up Files Interactively... -> Choose you backup scope...

Best Regards,

Check tape status as,

# mt -f /dev/rmt/

Backup
# tar -cvf /dev/rmt/ directory

Recover - Testing
# tar -tvf /dev/rmt/

Recover
# tar -xvf /dev/rmt/ .

See tar man page on EXAMPLES part.

You can do this with tar:

tar cvf /dev/rmt/0m dir

where /dev/rmt/0m is your tape drive (you may want to check this) and dir is the full path of the directory containing the logs (without a leading / - e.g. if you want to back up /var/adm/syslog you would put var/adm/syslog).

The cvf is:

c = create
v = verbose (echo to screen)
f = file (device receiving the backup).

To restore you would type the same command except you would replace the c with an x (extract).

For greater reliability you may want to use a proper backup product such as Data Protector - an HP product that provides much greater flexibility than tar.
