Re: amanda gtar question

To try and make my backups smaller I run a perl script that runs goes

The amrecover also works ok, if I needed to restore a file or a directory

for a user.host /export/fssnap/users/zhangj export-users-tar -1 localhost /export/fssnap/users/zhangs export-users-tar -1 localhost /export/fssnap/users/zink export-users-tar -1 localhost /export/fssnap/users/zjelonek export-users-tar -1 localhost /export/fssnap/users/zli export-users-tar -1 localhost /export/fssnap/users/zmullero export-users-tar -1 local


define dumptype export-users-tar {
    global
    comment "Full Backup of users  using tar"
    program "GNUTAR"
    maxdumps 10
}

But I ran into a major problem when I had to rebuild the entire "users" disk
because of a major crash.

The problem is that the user files in the backup tar file are relative to
/export/fssnap/users/username, which means I need to know and create the
directory name and permissions where the files will be placed on the disk

before I can restore.

I only wanted to make one pass through my backup tapes so I had to create a
script to manually read the first record of the backup tar file to get the
user/directory name, create the directory, cd to the directory and then

manually dd'ed and untared the file to the directory.

What I really need is for the backup tar file to be relative to
/export/fssnap/users.

QUESTION

Is there a way to force the relative path in the amanda tar command?



Use disklist entries in this form:

   host  unique_name   /top/level/dir  {
            base-dumptype
            include "./subdir"
            }
   host  /export/fssnap/users:zli  /export/fssnap/users  {
            export-users-tar
            include "./zli"
            }
   host  /export/fssnap/users:zmullero /export/fssnap/users  {
            export-users-tar
            include "./zmullero"
            }

The second arg must be unique in a disklist.  It can be whatever you
like.  I used the concatenation of topdir and subdir with
colon as separator between the dir and subdir, but you could also
use a slash (no space).

Remark:  when using vtapes, you are limited to those chars in that
unique name that the filesystem where the vtapes are located can handle.
E.g. many USB-drives use vfat, which *cannot* handle a colon in the
name.  You get a very obscure error message from taper in that case.
