ERROR: ZipArchive returns status: (ER_DELETED) Entry has been deleted

Hi,

First, thanks for this great plugin, It’s part of my default plugin set for any WP project!

Unfortunately, I had recently an strange issue that is reported in the error log e-mail that I receive every time a backup is generated. It seems to happen when compressing files as a ZipArchive. Here is a fragment of the error log report:

[24-ago-2014 03:10:31] Compressing files as ZipArchive. Please be patient, this may take a moment. [24-ago-2014 03:11:19] Restart after 48 seconds. [24-ago-2014 03:12:07] Restart after 48 seconds. [24-ago-2014 03:12:55] Restart after 48 seconds. [24-ago-2014 03:13:44] Restart after 49 seconds. [24-ago-2014 03:14:32] Restart after 48 seconds. [24-ago-2014 03:14:33] <strong>ERROR: ZipArchive returns status: (ER_DELETED) Entry has been deleted</strong> [24-ago-2014 03:14:34] Backup archive created. [24-ago-2014 03:14:34] Archive size is 232,45 MB. [24-ago-2014 03:14:34] 7222 Files with 346,96 MB in Archive. [24-ago-2014 03:14:34] One backup file deleted

As you may see, The error is reported, but a backup file is generated. What could be this causing this error? Any ideas?

Thanks for any help!
