It appears that Time Machine is retaining outdated backups of a device that I no longer use, raising concerns about storage space on my backup drive. Currently, I have Time Machine configured to back up my main internal drive, labeled as **Media**, and my external media drive, referred to as **iMac**.
A few months ago, I upgraded my media drive to a larger SSD. However, Time Machine is still showing backups of the previous drive, marked as **Media 1**.
This particular backup has not been updated since early April, and I initially thought that once Time Machine purged the last backup that included the old Media drive, it would free up storage space. Unfortunately, that hasn’t happened, and I find myself with only about ten days’ worth of backup versions remaining.
The backup drive has a total capacity of 4 TB, while the combined data from my iMac and Media drive amounts to roughly 2 TB. I suspect that the lingering **Media 1** backup is consuming valuable space, which contributes to the limited history of my backups.
I am wondering if there are steps I can take to resolve this issue. Do I need to wipe the backup drive completely and initiate a fresh backup to eliminate the old **Media 1** backup?
Any guidance on how to fix this situation would be greatly appreciated.
