Snapshop Pro Error first time used: PcLZIP file:media/2011/06 add failed - 10:

I have attempted to do a Snapshot Backup on my website but it has come up with an error on the second last line with 5% done on that line.

I didn't know whether I should put the full error on here as it gives a home path with username. Instead I will tell you the last part of the error which should hopefully let you know the error and why:

_backup/1447128222/pclzip-56416de871dbe.gz' has invalid filesize - should be minimum 18 bytes [code 10]

I have allowed Support Access if needed.
