Hi,

I got a strange phenomen after upgrading a two year old Backup and Recovery (VirtualServer Edition, or however it is called) to the latest relase.

First Issue: All Backup tasks didn't work anymore.
B+R was moaning about missing MS SQL Passwords. After that was fixed, it was still moaning about being unable to connect to the backup ftp-server (Linux Box, Debian 7 wheezy, pureFTPd, with exactly one user for acronis).

After changing the unmanaged depot to "ftp://server-ipwhatever:21" instead of "ftp://server-ipwhatever"; i could re-enter my credentials and it seems working again.

Backup "seemed" working and took only about a couple of hours. Validating the backup tool way more time - in fact, it is know at 100% validated and it is still not finished (it stays at 100% for at least half an hour or more).

In the pure-ftpd logfile I see lots of "restart commands" which are gratefully committed, every 256KByte or so....

Is this correct? With this amount of resume/restart commands it is totally clear to me, that performance will be exceptionally poor....

The firewall between the Acronis Server and the Storage Server is still the same as it was before the upgrade. ICMP is unfiltered, UDP/TCP is reachable.
On Acronis passive FTP is used - the backup itselfs is reasonably fast.
Downloading with the windows ftp cli-program is reasonably fast (nearly wirespeed) as well.

What's going wrong?

Thanks a lot for your help!

Cheers,

TheTeam
