Question. I have this plugin installed with the zip premium extension. My understanding is that the first backup is a full backup, and then the following backups are incremental. Is this correct?
Also, I ran my first backup and the result was good. I have a 387MB zip file with my code and sql files for the database. But I noticed the following in the backup log (I removed some identifying info):
16:29:09 : A total of 20MB of memory was used to complete this backup.
16:29:09 : A fatal error occured: Submitted input out of alignment: got  expected  (Status Code: 400)
16:26:57 : Uploading /******/html/wp-content/backups/blogs-backup-2012-12-20.zip in chunks.
16:26:57 : A total of 5909 files were processed.
16:26:47 : Approximately 95% complete.
16:26:41 : Backing up WordPress path at (/*******/html/).
16:26:41 : Creating zip archive.
16:26:28 : Creating SQL backup of your WordPress plugins.
16:26:27 : Creating SQL backup of your WordPress core.
16:26:12 : There has been no backup activity for a long time. Attempting to resume the backup.
16:20:34 : Uploading /*********/html/wp-content/backups/blogs-backup-2012-12-20.zip in chunks.
16:20:34 : A total of 5909 files were processed.
16:20:24 : Approximately 95% complete.
After it tried to upload the zip file in chunks, it seemed to timeout and start over. Then there is a fatal error, and then supposedly completes. Thankfully, it seems to have worked because I have a full zip file with the backup. But, I'd like to understand the process and what the error is and fix it, since I will be relying on this to protect my blog.
Appreciate any help, on what seems to be a very helpful plugin (assuming I can get this bit squared away).
