so, do you get that error immediately when starting the fbackup, or does it run for a while firtst?

I ask, because the message implies that you've filled a tape? Is that a possiblit?/

Re: fbackup Problem

You can do few things.

If you are getting this message immediately as soon as your backup starts, then it problem seems to be tape media, so you can use some other tape and see.

Secondly, it is also possible that your backup is not fitted in your tape and that is why it is prompting you for tape,

If you feel above steps is Ok , then try to take the backup from command line.

Re: fbackup Problem

So it could be possible that your backup is not fitted in your tape and that is why fbackup prompting you for tape.

simple test:- just try to fbackup few of the files e.g /etc/hosts, /etc/group and see.

Re: fbackup Problem

You are getting this message because your cardridge is becoming full, you need to insert the second cartridge and press enter.

You can also try to use a fresh new cartridge.

How much data are you traying to backup? DDS2 can only take 12/24 GB

Re: fbackup Problem

Let me make a correction,

DDS2 can only have 4/8 GB meaning 4 GB Native and approx. 8 GB with compression. You also have to know that compression ratio depends on your file types.

Re: fbackup Problem

This is normal when you try to store more data than will fit on the tape. The error message implies that fbackup wasn't run interactively. Someone will have to run fbackup from a login, then change tapes whenever requested and type y when the new tape is ready. Repeat aas many times as needed until fbackup finishes.

Re: fbackup Problem

Hi Blunt,

As per you, the error is due to Capacity of Tape Cartridge(only 4 GB), we need to put high capacity tape.

Can you help me in this, what is the high capcity supported by the " HP C1533A" Tape Drive.


Thanks,

Re: fbackup Problem

> C1533A

This is a DDS-2 tape drive and can store only 4 GB on a DDS-2 tape. With compression, you might get 5 GB but seldom will you get the 8 GB quoted by the ads. You cannot put a higher capacity tape (such as a DDS-3 or DDS-4) into the drive. The drive will reject the tape. DDS-2 is very old technology (apx. 1993) and writes at less than 1 MB/sec.

Here is a link that document HP tape drives and tapes:
