Try upgrading to 6.0.2 or go to 6.1.1 because Win2K and 6.0.1 are very slow.
Patch in 6.0.2 addresses this.

I'm afraid you can't decrease backup time of 350 Exchange Mailboxes.
Legato tells us that a number of 100 Exchange Mailboxes can be backuped in
adequate time.
The bottleneck is the API of the OS, not Legato.

Betreff: [Networker] Fast Exchange Mailbox Backup

Hi there,

does anybody has an idea to decrease backup time of Exchange Mailbox backup?
Configuration is following:
NetWorker 6.01 on a W2k with 2 x DLT 7000 in a 10 Slot Library SCSI
attached.
Exchange 5.5 SP3 on a W2k with NetWorker Client 6.01 and Exchange Module
2.05

Backup of complete DB (11 GB) with MSEXCH: takes about 30 min. Backup of
Mailboxes (about 350) takes over 8 hours. If we try to use the input file
with "nsrexcsv.exe -I input_file" no parallelism is used. If we try with
savesets like MSEXCH:MB Mailboxname parallism is used, but it works not for
all 350 mailboxes.

Any suggestions?

with best regards
