Changing TM Backup to a New Larger Drive

[0388279]

Hi All:

I have my Time Machine back-ups from my 2016 MBP going to drive that I have attached to my 2018 Mac Mini. I would like to increase the size of the TM drive. The back-ups in this configuration are .sparcebundle.

I have followed instructions from Apple's support: https://support.apple.com/en-us/HT202380 However, these instructions are for drives that directly attached to the Mac being backed-up and the back-ups in this configuration are of the type: Backups.backupdb

My attempts at following the instructions at Apple support except with networked drives have all failed.

Does anyone know if I can increase the networked drive size and maintain my old back-ups onto the new larger drive?

Thank you in advance.

The networked drive should have a sparse bundle file on it for the backup. Open that sparse bundle and inside it should be the Backups.backupdb file you can copy just like the Apple instructions say.

Hi WB:

What I did was copy the sparse bundle from the smaller drive to the new larger drive. Then I attempted to perform a Time Machine back-up to the new larger drive. This failed as Time Machine wanted to perform a first time back-up. What am I missing?

You need to open the sparse bundle and drag the Backups.backupdb file out of it and move it to the root of the drive.

Understood. I will give that a try.
