Restore fbackup tape on remote SUN server drive

[Pradeep Solanki_1]

Greetings

I received a DDS-3 tape in fbackup format, I don't have DDS-3 connected to HP-UX server. I tried restoring the backup on remote DDS-3 drive connected to a SUN
server, but it failed. Following options/command were tried. Is there any option to restore the data?

venus is L class HP-UX server where the data need to restored.
mercury is SUN server where the DDS-3 drive is connected.


# frecover -r -v -f mercury:/dev/rmt/0

It comes out without any error, the remote tape drive blinks once.


# dd if=/dev/rmt/0 ibs=10k |rsh venus "(cd /dcs_dump; /usr/sbin/frecover -r -v -f -)"

0+1 records in
2+0 records out
frecover(5418): not an fbackup volume; unable to read volume header
frecover(5414): abort selected

Thanks in advance

There is no fbackup/frecover for SUN, it is HP-UX only.
You may want to try:
dd if=/dev/rmt/0 of=/tmp/fred bs=10k
then ftp hte file to the HP system, and try to frecover fom it:
frecover -r -v -f venus:/tmp/fred

Otherwise, get a tape for your HP box, or get the tape sent in cpio/tar format

Hi pradeep,

Fbackup /frecover will work only in HP unix
platform.This is HP legacy backup command.


Try to extract the contents to you SUN server
local disk using dd and if successful transfer data to HP using ftp or rcp .

better take the backup using tar and then restore.

Hi,

I doubt you cannot "dd" a fbackup tape. fbackup tape is has
variable block sizes and end of tape marks.
This is the reason you the error when tried dd in a sun system.
In hp also dd will not work for a fabckup tape.

restore the data to a temporary directory on the hp-ux server

if you have room, create a tar file, ftp or sftp it to the sun box and then unzip it.

If however this backup was made on the sun box, its not fbackup format.

Are you sure the block size of the tape is 10k? According to the man-page the blocksize of the tape is 1k!

Also, I would suggest using the non-rewinding tape device on the sun. So try the first option, using the remote device on mercury, but use the non-rewinding:
# frecover -r -v -f mercury:/dev/rmt/0mn

Good luck

Dear All

Thanks for your suggestions

DD will not read the fbackup tapes as suggested by Thayanidhi. I don't have any other HP-UX server with DDS-3 tape.

I have found a external tape drive which I will try to connect with HP-UX server.
