Backup file generated is broken

Hi,

I am noticing that the backup files (both .zip and .tar.gz) are getting broken.

The log is showing only 2 warnings however there are no warnings in the log file displayed.

1. try for make list of files to backup….
2013/03/13 03:03.57: 6123 files with 162.7 MB to backup
2013/03/13 03:03.57: 1. try to create tar.gz archive file…
2013/03/13 03:04.30: tar.gz archive creation done
2013/03/13 03:04.30: Archive size is 43.69 MB <————-
2013/03/13 03:04.30: 1. try sending backup to SugarSync…

this is the log of a test case I just did to upload .zip to an FTP:

2013/03/14 00:45.28: 1. try for make list of files to backup….
2013/03/14 00:45.32: 6260 files with 160.15 MB to backup
2013/03/14 00:45.32: 1. try to create backup zip (PclZip) archive…
2013/03/14 00:46.09: Backup zip archive create done
2013/03/14 00:46.09: Archive size is 47.78 MB
2013/03/14 00:46.09: 1. try to sending backup file to a FTP Server…
2013/03/14 00:46.10: Connected to FTP server: xxx.net:21
2013/03/14 00:46.10: FTP Client command: USER xxxx
2013/03/14 00:46.11: One old log deleted
2013/03/14 00:46.11: Job done in 46 sec.

Uploaded would be a file of 43.69MB – but a corrupted archive. I tried also posting to another FTP server.

The error on the archive is: !

D:\Projects\xxx\xxx-live-bkp\backwpup_2_2013-03-14_00-45-25.zip: Unexpected end of archive

Same problems

Any ideas where I can begin to test / search for answers please?
