Hi,

I would like to view only the contents of a backed up tape using fbackup. I do not want to restore the filesystems...please help me to find out what command do i need to give to check the contents of the tape.

Thanks,
Jim

The frecover -I /xxx/yyy/file.list -f /dev/rmt/xxx will do the job. Man frecover.

From the man page for frecover

issue the command "man frecover" for the full info

-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).

The command you listed should display its results to screen. you can redirect the output to file with ">"
frecover -N -v -f /dev/rmt/xxx > /tmp/aaa

if i give the command

frecover -N -v -f /dev/rmt/om > /tmp/aaa its giving me an error which reads like i need to give some other options that i must specify like V, I, x, r or R

Please advice

The exact error it is giving you would be much more helpful that just "...its giving me an error which reads like i need to give some other options that i must specify like V, I, x, r or R"

try

frecover-x -vN -f /dev/rmt/om > /tmp/aaa

The command i gave is:

# frecover -N -v -f /dev/rmt/om > /tmp/aaa

frecover(3208): must specify at least one of V, I, x, r, or R
frecover -r [-hosvymFNOX] [-c config] [-f device] [-S skip] [-E extarg]
frecover -R path [-f device]
frecover -x [-hosvymFNOX] [-c config] [-e path] [-f device]
[-g graph] [-i path] [-S skip] [-E extarg]
frecover [-I | -V] path [-vy] [-f device] [-c config]
-{r,x} - full/partial recovery
-{I,V} - write index/volume-header to path
-{F,X} - flat/relative recovery
-{i,e} - specify a path to include/exclude
-{g,c} - specify a graph/configuration file
-{N,h} - No files recovered-Only verify/graph information
-R - continue an interrupted session
-f - specify an input device
-o - overwrite existing files
-v - verbose mode
-y - answer yes to all questions
-S - specify a file for skipped blocks
-s - sparse file recovery
-O - set ownership of files to the user running the recovery
-m - Print marker information (checksums, filemarks, setmarks)

Hi Jim:

> if i give the command

frecover -N -v -f /dev/rmt/om

...would yield:

...must specify at least one of V, I, x, r, or R

Hence, do that: add either -I /tmp/findex' or simply '-N'. Also, fix the 'om' to be '0m' in your tape device specification!
