Eclipse was running unattended for a couple of days and ran out of heap space. After restarting the task list was not restored.

Don't suppose you still have any of those smaller backup files kicking around? Might be worth looking at the contents to see whats missing and/or what the tasklist contains.
Well, it's unpredictable when the backup fails. I am pretty sure the backup will simply stop adding files once it runs out of memory and close the file.

Created attachment 146789 [details] patch

The patch changes the backup operation so that it propagates exceptions which are now handled in the backup manager. In case of an exception during backup the corrupted backup file is deleted to avoid confusion. I have committed this to the service branch and head.
