How do I backup the rest (inside files). I mean when for instance I backup /var/ does this mean that I back up everything inside the /var directory including all the sub-directories?

So I have several backups on the same tape. When I put the tape on and do a ufsrestore, you see only the first backup.(I suppose I have to rewind the tape before the restore , correct?

what happens when I do a ufsrestore -i
Am I able to choose ??

Thank you for your help

1) Yeah ufsdump will get all the files and subdirectories of /var provided that they are all in the same filesystem. If you create a separate mounted volume called /var/adm, well now you have to dump that separately. When you back up root, you get all of /bin and /lib, and so on. But you you still need /usr and /var as separate runs.

2) Yeah, you would need a rewind if you go to the restore immediately after the backup. Usually the restore comes long after the tape has been removed from the drive.

3) Yeah, the -i will let you pick and choose...a very cool feature.

amverify

AMVERIFY(8)						      System Manager's Manual						       AMVERIFY(8)

NAME

       amverify - check an Amanda tape for errors

SYNOPSIS

       amverify config [ slot [ runtapes ] ]

DESCRIPTION

       Amverify  reads	an  Amanda  format  tape  and makes sure each backup image can be processed by amrestore and, if possible, the appropriate
       restore program (e.g. tar).

       Amverify runs amrestore on each file of the tape and pipes the output to a restore program (if available) with an option to create a  cata-
       logue of the backup.  The catalogue itself is discarded.  Only the success or failure of the operation itself is reported.

       If  the	backup image cannot be processed by the restore program, e.g. if it was written on a different operating system, the image is sent
       through dd to /dev/null.  This still determines if the tape is readable, but does not do any internal consistency check on the image.

       If config is set up to use a tape changer, the slot argument may be used to choose the first tape to process.  Otherwise, the current  slot
       is used.

       The runtapes configuration parameter determines how many tapes are processed unless it is specified on the command line.

       See the amanda(8) man page for more details about Amanda.
