I try to do a complete backup (db, files, plugins etc) to dropbox. There is a warning creating the zip file:
[02-Apr-2013 11:20:13] Compression method is ZipArchive
[02-Apr-2013 11:26:14] WARNING: Job restart due to inactivity for more than 5 minutes.
Then it transfers the file to dropbox and the file is 2.5MB. The Whole site is 250MB and I expect the zip file to be about 150MB.
(Tar and gz option doesn't work)
