Hi TSM-development,
my situation
============
1. we are an AFS-site, where the user's HOME's are in AFS and every
user has it's own filespace, resulting in ca. 20000 filespaces.
2. A normal filespace has the following naming:
/afs/tu-bs.de/usr/usrXX/individual-user
whereby the XX is actually the resp. user's UID modulo 100, i.e.
let XX=$UID%100
3. The actual backup is done in 4 streams in parallel, i.e.
stream A processes /afs/tu-bs.de/usr/usr0 ... /usr24
stream B processes /afs/tu-bs.de/usr/usr25 ... /usr49
stream C processes /afs/tu-bs.de/usr/usr50 ... /usr74
stream D processes /afs/tu-bs.de/usr/usr75 ... /usr99
in a loop over the given range of "usrXX", checking wether the
AFS-volume of the resp. user has been changed during the last 3 days.
4. This process works fine, i.e. we process all our AFS-USER-HOMES in
about 2-3 hours on an IBM H70, 1GB, 100MBit Ethernet
Now the problem
===============
5. If a user tries to do a restore via a dsm/dsmafs-wrapper, which sets
an environment-variable called USER_DIR, which is subsequently used
in dsm.sys via
VIRTUALMOUNTPOINT ${USER_DIR}
and in dsm.opt
DOMAIN ${USER_DIR}
the user is then presented with the ca. 20000 filespaces of user's
he isn't interested in and finding HIS filespace is really not very
much fun.
6. If we create a 1-line "$HOME/.adsmrc" containing
FindStartPath.Restore=$USER_DIR
we can tell the user to use the "looking glas"-icon to start with
the propper path in the "Find Files (Restore)"-window which makes
life much easier.
Now my questions:
=================
7. Is the time- AND resource-wasting build-up of the ca. 20000 presented
filespaces necessary or is there a shortcut in just presenting the
requested filespace ( given by VIRTUALMOUNTPOINT / DOMAIN ) ?
8. The feature in 6. is undocumented. Please give Your comments on this.
Hope for some answer
