I recently had some issues with backups failing during the backup in
some strange way, which caused all files after that point to be marked
as "deleted". This caused the following backup to need to re-transfer
all of those files again the next time. (using rsyncd over ssh tunnel as
the backup method).
Please see the latest log file displaying the error:
- From the beginning of the backup:

Since this was an incremental backup, the backup isn't saved, and so
things should work normally tomorrow. However, in the past, if this had
been a full backup, it was being saved as a partial, and hence causing
the re-transfer of all the data that had been marked as deleted.
Just thought I should provide an update on how things were going, as it
isn't possible to cause the failure on demand and I didn't want the
'fix/patch' to be forgotten/missed.

Adam
