If I use fbackup to backup, how can I read what I just backed up without actually writing anything on the disk. Any help will be greatly appreciated.
Solved! Go to Solution.

Re: Frecovery question
Simple, do the frecover just as you would for real but add the -N flag. This does everything EXCEPT write to disk.
Man frecover for details.

Re: Frecovery question
Using 'frecover' there are two ways. The "quick" method is to use the '-I' option which simply reads the index on the tape. This may not be totally accurate since the index is built and written by 'fbackup' *before* files are actually copied.
The better option is to use the '-N' and '-v' options together to actually read the tape and list its contents, but *not* (-N) perform an actual recovery.
# frecover -N -v -f /dev/rmt/0m > /tmp/myindex

Re: Frecovery question
# frecvoer -Nv -f /dev/rmt/?m
Should read the whole tape, NOT restore anything and but give you output on the screen of all the files.
-v Normally frecover works silently. Verbose option. Displays the file type and name of each file processed.
-N (no recovery) Prevent frecover from actually recovering any files onto disk, but read the backup as if it was, in fact, recovering the data from the backup, producing the same output that it would on a normal recovery. This option is useful for verifying backup media contents in terms of validity (block checksum errors are reported), and contents (a listing of files can be produced by using the -N and -v options together). Note that the listing of files produced with the -N and -v options requires the reading of the entire backup, but is therefore a more accurate reflection of the backup's contents than the index stored at the beginning of the backup (which was created at the start of the backup session, and is not changed during the course of the backup).
