Hi.

I have studied a code a bit and had a chat with skodak. The message Incorrect string "needed" ... is not a problem in fact. It is just a metter of format of SQL table mdl_backup_ids.

When backing up users, Moodle saves some serialized information into the field "info", e.g.:
s:14:"exists,needed,";
but in some cases, the value of "info" can be unserialized - just plain "needed". Skodak considered this as an issue and wanted to force somebody to fix saving plain "needed" into the SQL - that is why the error emerges. But it is just a sort of warning for developers. The backup should continue normally.

Please describe more details about the problem with the backup. otherwise I propose to close as "not a bug".

Closing as duplicate of MDL-13641. Thanks for report.

We'll serialize/unserialize properly in that bug.
