fbackup

[Michael Poland_3]

I've found that fbackup does not appear to do what's reported. We use a Sony AIT-2. Please see the examples below:
Example 1.
----------
# fbackup -f - -i /101/101/tttutl -v > /dev/rmt/0m
fbackup(1004): session begins on Tue May 10 13:56:20 2005
fbackup(3024): writing volume 1 to the output file -
1: / 16
2: /101 1
3: /101/101 4
4: /101/101/tttutl 1
5: /101/101/tttutl/checkfile 1
6: /101/101/tttutl/tutl947101.bdt 8
7: /101/101/tttutl/tutl947101.bid 48
fbackup(1005): run time: 1 seconds
fbackup(3055): total file blocks read for backup: 79
fbackup(3056): total blocks written to output file -: 120
# frecover -x -N -v -f - < /dev/rmt/0m
#

i.e. nothing reported.

Example 2.
----------
But if we run:
# fbackup -f - -i /101/101/ttttxt -i /101/101/tttutl -v > /dev/rmt/0m
fbackup(1004): session begins on Tue May 10 14:26:30 2005
fbackup(3024): writing volume 1 to the output file -
1: / 16
2: /101 1
3: /101/101 4
4: /101/101/ttttxt 4

Any ideas as to why it should not report anything on tape under the first example?

Hi Michael,

I have never seen using fbackup with a redirect (>) to device file. Have a look at the man pages of fbackup and frecover.
Here is what i would suggest to use

#fbackup -v -i /101/101/tttutl -f /dev/rmt/0m

Cheers

Can't do that format as the SOny AIT is not recognised.

[Michael Poland_3]

This is what happens if I try the -f switch:

# fbackup -v -i /101/101/tttutl -f /dev/rmt/0m
fbackup(1004): session begins on Tue May 10 17:00:36 2005
fbackup(3038): output file /dev/rmt/0m is not a valid device file for backup
fbackup(3019): would you like to enter a new output file?
n
fbackup(3022): would you like to continue this session?
n
fbackup(3004): writer aborting
fbackup(1002): Backup did not complete : Reader or Writer process exit
