Hi all,

last week we survived a RAID-Crash (6 of 8 HDs bad blocks - don,t
ask...), and restored all data completely and timely, to my surprise... :)

Afterwards, I took a closer look at the restore process, and found the
following, which irritates me quite a bit:

Given a directory on drive D: of the W2k-Server by the name of
"backups". Into this dir, a PRESCHEDULECMD is run, which copies dumps of
databases running on that machine into this directory. This is done by
both, copying a single file as well as complete directories there.

After that, an incremental backup of all of D: is run. The backup copy
group applied looks like this:

Backup Copy Groups : STANDARD STANDARD STANDARD
   STANDARD

Policy Domain Name
                                    STANDARD
          Policy Set Name
                                    STANDARD
          Mgmt Class Name
                                    STANDARD
          Copy Group Name
                                    STANDARD
          Versions Data Exists
                                    2
          Versions Data Deleted
                                    1
          Retain Extra Versions
                                    30
          Retain Only Version
                                    60

and is (of course) derived from the default settings, which seem
sufficient to our needs and space limitations of the lib we have.

I would expect to be able to restore, in the worst case, every file to a
timespan of up to 60 days after deletion and, if a file had changed
multiple times, up to two versions before the current one, up to 30 days.

Now, if I fire up the GUI and take a look at different points of time at
which (to which?) I could restore the folder or files to, I see (view
also deleted files is enabled) today the folder and files, yesterday the
folder with the little blue cross (for deleted?), and the day before
yesterday nothing. The folder "backups" is not there.

If i use the CLI and type

tsm> query backup -pitt=06:00:00 -pitd=20.07.2003 d:\backups\

I still get listed a whole bunch of files, of which I assume that they
are all younger than 6am, 20.7.03 - which is what i would expect. Note
that currently I would not know how to restore such a state using the GUI.

Is the difference in behaviour between GUI and CLI a bug, a feature, or
something which I don,t understand since I am missing something?

Thanks in advance for any input,

kind regards, tobi... :)
