fbackup

[j773303]

Is it possible use fbackup command to backup the data in the same tape from the 2 machine?
For ex:
host2: fbackup -i /tmp -f host1:/dev/rmt/0mn
host1: fbackup -i /tmp -f /dev/rmt/0mn

I have try this behavior, if seems tape would rewind even /dev/rmt/0mn

Right - fbackup rewinds a tape before starting to write to it. Therefore you cannot have two backups on one tape.

Hi,
Have a look at the man pages of fbackup you'll find there written as

fbackup should not be used with no-rewind devices, for example,
/dev/rmt/0mn.

Hi there,

'fbackup' command is not design to append the files.

You can use 'tar' command with 'r' option for append the files or 'dd' command.

Please goto knowledge mine with docID : CJW9304231450 about 'Comparison of Backup Methods and their supported features' for your reference.

Hope this information can help you.

Best Regards,

Hi
to backup more fbackup-session on one tape try this example:
#backup
fbackup -v -i /var/tmp -f - | dd of=/dev/rmt/1mn bs=10240
fbackup -v -i /tmp -f - | dd of=/dev/rmt/1mn bs=10240
# Restore
mt -f /dev/rmt/1m rew
dd if=/dev/rmt/1mn bs=10240 | frecover -vf - -I /tmp/ddd.txt
dd if=/dev/rmt/1mn bs=10240 | frecover -vf - -I /tmp/ddd.txt
#

can you use remsh to execute fbackup as remote command (output to stdout?)
