The Problem
After migrating the entirety of a a Backups.backupdb to a new hard drive as recommended by Apple by simply copy-pasting within Finder between two local disks, Time Machine encountered an interesting issue. Though it successfully used the new disk to backup whilst recognizing the old backups, instead of creating another incremental backup (as expected normally), it instead created a full backup. As a result, the old backups were deleted from the new drive to make room for the full backup (I still have the original drive and all of its data.) This is not the desired result for me, as I would like to keep my old backups.
Attempted Solutions
This question seems to indicate some similar problem, but has no resolution. Using BackupLoupe on the new disk per this post simply confirms this.
Additional Info
Running OS X 10.11.4 on an Early 2009 iMac. Original drive is 2TB Western Digital My Book Studio (over Firewire), new drive is 2TB Western Digital My Passport (over USB 2.0.)
Backup.log edit
At the request of @klanomath, I've added the logs for the relevant backups. The first log is that of the last normal backup. The second log is that of an abnormal backup.

Extended Attributes
After doing some research, it appears that extended attributes of relevant files are where the keys are held. Though FSEventIDs were indeed the culprit as @klanomath suspected, editing the main FSEvents database isn't enough alone, according to this Superuser post.. (I can't quote it here due to character limits.)
However, looking at the SnapshotVolumeFSEventStoreUUIDs using xattr -l, they appear to be unique with each backup, regardless weather it's a full backup or not. SnapshotVolumeLastFSEventID doesn't seem to have the same format as SnapshotVolumeFSEventStoreUUID, instead being a much shorter string of characters. Only SnapshotVolumeUUID appears to remain consistent.
Unfortunately, I'm at a loss on how to cure this problem. Though I think it might be possible to postpone it, besides adding more space, I'm not sure if there even is a way to prevent it.
