Description of my issue:
php error in log.
The backup status window shows that backup is complete, except the warnings show that a directory is unreadable. I have verified with the hosting company (Arvixe) and they confirm all permissions are set to full use, there is plenty of disk space (well below my limit).
Troubleshooter - ALICE has error with Backup archive writing issues (Could not open archive file for append.)
I don't trust the backup is valid, as the backup file used to be around 30Mb, and now it is only 800kb.
Based upon all the reading, I am assuming this has something to do with a file permission, or php setting that I need to address with the hosting company, but I don't know what to ask them to adjust?
