I am running EV 7.5 File Server archiving on a server at a remote location.  Bandwidth is not great, and my server is underpowered (2GB RAM and 1 CPU) so I know that is part of the issue.

My archiving rules are:
Do not archive - file is one of (exclusion list)
Archive all other files

Time for BOTH rules is
Last access time is older than 1 year
last modified time is older than 3 years

Exclusion list is pst, ost, pab, oab, mdb, ldb, mde, mdw

The job has been running for about 7 weeks on this schedule:
4 hours/night weekdays
6 hours per night Sat
8 hours per night Sun

The job never finishes.  It started out archiving about 2GB per night weekdays and 3GB per night on weekends
Now the typical result is less than 300MB archived.

The exclusions encountered are 155 items at 2496MB

My question is how to improve performance through tuning the rules.
Am I right to have the same Times filter on my do not archive rule as my archive rule?
Is there another way to tune this to exclude files not access in ocver 1 year?
is there a way to have it pick up where it left off the previous night?  It always starts at the beginning.

I imagine it will eventually get all the way through the folder structure in one pass, but I am also archiving mail and I need to start looking at Sharepoint soon, so my schedule needs some space!
Thanks!
