[cisco-voip] UCON DRS Issues

[Jobe Gates]

Just had a chance to try this and it does create a separate .tar file for
each mail store.  This is on 7.1.3.  Looks like there's a limit of 5 stores.

An administrator with the required permissions can create up to four
additional mailbox stores. Each additional mailbox store includes:

•Another mailbox-store database for information on voice messages that are
saved in that mailbox store. The database is presized for an average of
approximately 40 messages each for 10,000 users, or about 1.25 GB. (The
database application currently being used for Connection cannot dynamically
resize a database after it is created.)

•Another operating-system directory for the voice message WAV files and
other message attachments saved in that mailbox store.

Thanks,
Jobe

I haven't tried that yet to see if it would help. Does each UCON mailstore
get backed up separately?
