server A whith one DLT4000,
we want to backup all data
of server B to server A tape
How to do this ?
It's possible we need to restore one or few file from

Should we use util "fbackup" ?
Thank's a lot .

Hi,

One point to bear in mind is that using fbackup/frecover with a remote tape device means that fast search markers are not written. Recovering individual files will therefore be slower than using a local drive.

Darren.

Hi,

You can use fbackup to backup to a remote tape drive
eg fbackup -f :/dev/rmt/0m -i /

You can restore selective files using frecover.

Hi,

fbackup is capable of using remote drives and it comes with your OS so this is an pretty good choice for data backups.

But keep in mind that you have to have an running OS to use it. If you want to backup your server and not only the data you should consider using ignites make_tape_recovery.

This will backup your OS and your configruations. In case of an desaster you can restore your server from this tape. Then with the running OS you can restore the data from the remote drive using fbackup.

Disadvantage is that make_tape_recovery requires a local tape drive.

Perhaps you have an additional DAT drive to use as a system backup drive and you use the DLT as a data backup drive.

Hope this helps

Regards Stefan
