Time machine cannot backup after initial backup on samsung T7

Question

Time machine cannot backup after initial backup on samsung T7

I'm running macOS 10.14.6. I successfully backed up using time machine to my Samsung SSD T7 five months ago but I cannot backup to it when I tried using time machine now.

I get the "preparing backup" stage but then time machine stops the backup. When I check my hard drive, I do get updated .inProgress file.

I have already tried to delete the .inProgress file and restart but it fails every time. The .inProgress file is less than 1 MB when it fails.

MacBook Pro 13″, macOS 10.14

Start with this..

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Q - " I 'm running macOS 10.14.6. I successfully backed up using time machine to my Samsung SSD T7 five months ago but I cannot backup to it when I tried using time machine now. "

A - This issue might be, TM Backup Utility is Processing 5 Months of Snap Shot before it can actually Transfer the 5 Months of Snap Shots to the Samsung T7 SSD

Thank you - after booting in safe mode it'll start backing up, so I tried to back up in normal boot. However, it makes some progress and then the backup fails (About 1/2 of the way).

Should I only back up in safe mode? And should I delete the .inProgress file every time I restart?

Have you tried Disk Utility (Applications/Utilities folder) to check the health of the SSD? It might need some first aid. Do you have another external drive that you can also use for Time Machine?

Note that Time Machine will happily use several external drives for backups and alternate between them.

In any case there is mixed advice about leaving SSDs unplugged for several months. Some say they should be powered up from time to time.
