Well rol,
let's start with this issue before we come to the issue with the not working Restore. I manage several sites with the version 0.3.1 on WP 2.2.3.
My Permalinks are standard. There is non .htaccess-file in place (there was one but I head problems with it which disapearded after deleting the .htaccess-file).
I have three full backups in my backup-directory which are not shown in "Manage Backups" (Backups verwalten). In there, only the SQL-Backups are shown. These full backups seem to be ok. So, I assume that the copy worked alright and that the crash comes somewhere later.
I can't download the SQL-backups within BackUpWordPress because they lead to a file like "farzCaqzS" without extension. I have 10 files like this in my backup-directory. There are all 4MB large and seem to be the SQL-Backups listet in "Manage Backups". When I copy these files manually to my Linux-Desktop (Ubuntu 7.04), my system seems to see the file as an archive but can't open it, even not with the extension "tar.gz".
And now the really funny thing: On this site, let's call it "BGM", I have ftp-access only and I am not able to rename files. I am only able to delete and copy files.
Does it ring? (You know, what I mean - I don't know whether this can be translated word by word from German to English :-)
I will check soon with another site, let's call it "SW", where I have full ssh-access and no problems with renaming files.
Cheers - Gerhard
