I have 3CX Version 15.5.3849.1 installed to Windows 10 Pro. Recently I updated Windows 10 Pro to 1709 version and after that I have problem to backup in Google Drive (no problem with FTP or local backup). It looks that it uses many network resources to upload backup for a long time (my upload speed is 3MB/sec and the backup file is about 20MB). Βackup does not completed successfully the most of the time and create empty .zip.tmp files in GDrive. 1.Do you any idea why this happen? 2.Is there any log file in 3CX that I can find more information about the problem? 3.How can stop the backup if I have similar problem?
