fbackup usage file larger than 2GB

[Gus Mestousis]

I tried to use SAm, but it wouldnt see the file. Can anyone provide me with the correct command to do the following:

Use fbackup to backup a 3GB File to a DDS drive

File: /home/test/backup.tar.Z
Device: /dev/rmt/0m

I assume it is as follows:

fbackup -f /dev/rmt/0m -i /home/test/backup.tar.Z

Is this correct?
Thanks!

Hi,

What error are you seeing?
Exactly what tape drive and tape are you using?
DDS
DDS2
....
There is a limitation on how much data can be
written depending on the tape and drive
combination.

The command you are using should work,
but I would place the syntax as

# fbackup -i /home/test/backup.tar.Z -f /dev/rmt/0m

It is a DDS3 Drive using a DDS2 tape. When trying to use SAM, it wouldn't let me specify that file. But it does seem to work via the command line.

Thanks!

Is there any way to check the status of the job, while it is in progress?

When I run top, it shows that it is in sleep mode. and using up a very small % of CPU.

Can the process be speeded up?

Thanks!

Hi,

The process will not really use a great deal
of CPU as you are actually reading from a disk
onto a streaming tape. It will also depend on
the type of machine/SCSI/disk combination
your using to how fast it will actually
write to tape.
