Hello Vice Versa community!

I am using Vice Versa Pro to sync to server shares over internet. Both servers are connected by a 8MBit SDSL connection to the internet, using a company VPN.

The Sync job is scheduled for every evening out of office hours.
Checking the log file after a successful sync, it shows that checking the volumes takes 2 days (650,000 files, 572,55GB).
The changes are only 145MB, 2,000 files - copying takes just some minutes.

Is there any way to shorten/optimize the checking phase?

Best regards, Mathias

Hi, what version of SMB do you have for that connection? In the log, is most of the time taken to scan a particular location? thanks

Sorry for the late reply - will now register to receive notification!

I don't know which Version of SMB is in use. Have to check with Server-Team.
It's not a particular location as long as I can see from the logs. We have three jobs running with some folders each and the overall scan takes that long.

Code:

An old log ... don't know why there is an error during scanning - connection is stable but this message is in every log.

I now checked the SMB Versions. As one server has 2008 R2 and the other 2012 the communication version falls back to SMB 2.1 - right?

OK. So is the SMB Version the root cause for the slow checking?
