This is the backup script used to backup the files:

Code: 
find /usr/cimage/shared \
     /usr/cimage/mtserv511 \
     /san_ora_bkup \
     -print > /tmp/daily_backup.list

cat /tmp/daily_backup.list | backup -iqf/dev/rmt0.1
#
if [ $? -eq 0 ]
then
  DATA_BACKUP=ok
else
  DATA_BACKUP=bad
fi
#
#-----------------------------------------------------------------------
#
# Determine which day of week it is and set the appropriate -Level for
# incremental backup.
#
DOW=`date | awk '{ printf $1 }'`
case $DOW in
  Fri) LEVEL=1;;
  Sat) LEVEL=2;;
  Sun) LEVEL=3;;
  Mon) LEVEL=4;;
  Tue) LEVEL=5;;
  Wed) LEVEL=6;;
  Thu) LEVEL=7;;
esac
#
#------------------------------------------------------------------
#
# unmount /image1 and /image2 and take an appropriate backup by i-node
#
unmount /image1
unmount /image2

backup -$LEVEL -uf /dev/rmt0.1 /image1

if [ $? -eq 0 ]
then
  IMAGE1_BACKUP=ok
else
  IMAGE1_BACKUP=bad
fi
#
backup -$LEVEL -uf /dev/rmt0 /image2

if [ $? -eq 0 ]
then
  IMAGE2_BACKUP=ok
else
  IMAGE2_BACKUP=bad
fi
#
mount /image1
mount /image2

i used this commmand to view the backed up files:
Code: 
restore -Tdvqf /dev/rmt0 > restore.log

but i couldn't find /image1 and image2 files in this tape :(

i'm trying to restore a file that was supposed to be in /image2 and the tape that i've got is the one backed up on Sunday 23 of April ( Sun) LEVEL=3;; )

I was doing this the whole day today so any clue is appreciated

regards
Khalid

It looks as if /image2 is on the second logical tape, in which case rewind the tape, issue an

mt -f /dev/rmt0.1 fsf 1

(0.1 referring to the no-rewind device) and then try your restore. Good luck.

Thanks KenCunningham

I did what you said and i issued this command

Code: 
restore -xdvqf /dev/rmt0 /image2/images/vault/777/192741.dwg

but i got this message:

restore: 0511-155 Cannot use the d flag to restore backups by i-node.

Should i just remove the d flag and reissue the command?

Yes, -d can only be used for backups done by file name. I assume the tape will have rewound again, so you will have to redo the mt -d /dev/rmt0.1 fsf 1 as above. You might find that you need to specify

/image2/images/vault/777/192741.dwg

as:

./image2/images/vault/777/192741.dwg

instead.

i guess you might mean mt -f not mt -d right?

any way, i'm doing it right now with -f and i will see what will happen

Thanks

i got the following error :(

Code: 
[edms]{root}/>mt -f /dev/rmt0.1 fsf 1
[edms]{root}/>restore -xvqf /dev/rmt0 ./image2/images/vault/777/192741.dwg

yes there is a log but it only shows if the backup was successfull or not!!!

it doesn't show the files that were backed up if that what's in your mind!

oh i've changed rmt0 to rmt0.1 and see what happened:

Code: 
[edms]{root}/>restore -xvqf /dev/rmt0.1 /image2/images/vault/777/192741.dwg
Verifying archive and initializing maps.
The dump date is Mon Apr 24 01:18:18 Bahrain 2006.

./image2/images/vault/777/192741.dwg is not on the archive.

You have not read any media yet.
Unless you know which volume your file or files are on, you should start
with the last volume and work towards the first volume.
Specify the next volume number: ^Crestore: 0511-350 The restore is interrupted.
        Do you want to continue? [ yes or no ] n

does that mean the file doesn't exist on this tape? or should i put something when it asked me for the volume number??

you could do a tcopy of the tape to make sure there's something on there.

ex. tcopy /dev/rmt0

won't tell you content, but will verify that something's actually on the media, how much, etc...

That's what i've got :(

Code: 
[edms]{root}/>tcopy /dev/rmt0

tcopy: File: 1; End of File after: 0 Records, 0 Bytes.
read: There is an input or output error.
tcopy: The end of the tape is reached.
tcopy: The total tape length is 0 bytes.

and its still hanged waiting for something i beleive

hmm, your output from tcopy shows two files, but you should have 3, including the backup command at the start of the script.

anyway, you can also restore interactively:

rewind the tape : mt -f /dev/rmt0 rewind

get in restore : restore -if /dev/rmt0.1

quit, if your file is not there. the tape will advance to the next file. repeat the restore command until you find the file, or run out of tape images.

if everything goes well, you'll get a command prompt and will be able to list files, and cd into directories. you can also mark the files you want for restore. from the man pages for restore:

cd Directory
Changes the current directory to the specified directory.

add [File]
Specifies that the File parameter is added to the list of files to extract. If File is a directory, that directory and all the files contained in it are added to the extraction list (unless the -h flag is used). If File is not specified, the current directory is added to the extraction list.

delete [File]
Specifies that the File parameter is to be removed from the list of files to be extracted. If File is a directory, that directory and all the files contained in it are removed from the extraction list (unless the -h flag is used).

ls [Directory]
Displays the directories and files contained within the Directory parameter. Directory names are displayed with a / (slash) after the name. Files and directories, within the specified directory, that are on the extraction list are displayed with an * (asterisk) before the name. If verbose mode is on, the i-node number of the files and directories is also displayed. If the Directory parameter is not specified, the current directory is used.

extract
Restores all the directories and files on the extraction list.

pwd
Displays the full path name of the current directory.

verbose
Causes the ls subcommand to display the i-node number of files and directories. Additional information about each file is also displayed as it is extracted from the archive.

setmodes
Sets the owner, mode, and time for all directories added to the extraction list.

quit
Causes restore to exit immediately. Any files on the extraction list are not restored.

help
Displays a summary of the subcommands.

Another attempt :(

Code: 
[edms]{root}/>tctl rewind
[edms]{root}/>mt -f /dev/rmt0.1 fsf 2
[edms]{root}/>restore -tvqf /dev/rmt0.1 > restore1.log
Synchronizing restore again; skipped 1232 blocks.

dir     272384  ./images/vault
dir     169987  ./images/vault/775

but i still don't see 777!!!

but i'm sure that there are files created on the 22 April which should have been backed up:


These are the files created on that date:

Code: 
[edms]{root}/image2/images/vault/777>ls -al | grep "Apr 22"

Thanks Breslau

That's what i get :(

Code: 
[edms]{root}/>mt -f /dev/rmt0 rewind
[edms]{root}/>restore -if /dev/rmt0.1
Please mount volume 1 on /dev/rmt0.1.
        Press the Enter key to continue.

restore: 0511-154 Cannot use the i flag to restore backups by name.

you seem to be running the restores correctly. so, if you go through the entire tape and you can't find your file, then for some reason it did not get backed up.

backing up to an attached tape drive is not always reliable. you could try tapes from other days if it is possible that the files would have been writen to tape then.

we switched to an enterprise backup solution 4 or 5 years ago and have been much happier with the results.
