Error: Plesk Backup and logs

[atinoco]

Guys I've been getting multiple errors with the plesk backup tool when doing my weekly plesk full backups.

I get multiple messages like this one:

The process cannot access the file "c:\inetpub\vhosts\puntoweb.com\statistics\logs\access_logs" because it is being used by another process.
Abort dump?

when selecting NO to the about dump dialog, the backup process seems to skip the file and continue with the backup process, this message repeats many times for multiple log files on some of the domains. I found out that restarting the server (something not very desired) before the backup process seems to minimize the amount of these "abort dump" messages but i usually get 1 or 2 even after a system restart.

anybody experincing these kind of problems? any suggestions or solutions? I don't feel like this is right.

thanks in advance.
