time machine no longer backing up on 13.2.1 M2 Pro

Been through hours of tech support no solution.

brand new M2 Pro running 13.2.1 using Samsung T7 2TB ssd for time machine backups. Nothing else on the external drive, loads of space (1.5 TB free), formatted APFS correctly, first aid shows no issues, have wiped and retried multiple times, wiped and used Time Machine to back up on identical different machine and worked fine.

Time machine performed initial backup fine, updated hourly for 2 weeks, and will no longer back up.

Is very slow, bogs down, stalls out somewhere between 57% and 65% and will not progress no matter how long (days) I leave it.

Apple support has no ideas for me. Can anyone help?

MacBook Pro 14″, macOS 13.2

Perhaps to try a different new external storage drive

and create a new Time Machine backup there.. may

be an answer of a sort. ~ Hardware can fail regularly.

We'd hope the cure would be so simple. Without repeats!🍄

Curious to know if any format was applied to the new external drive,

or if macOS was allowed to put whatever it wanted there, instead.

Sometimes those details can be important; as these newer Mac's OS

have different rules and higher level security. Also some parts of the

System are highly protected from incursions, compared to older Macs.

I've been outdoors here trying to de-ice solidly frozen rain gutters;

from step ladder on uneven terrain.. I'm indoors to get warm, and

also get another pair of dry gloves, since removing broken icy bits

from the gutter, gets my gloves soaked. And hands get froze, too.

So it's time to go back out there for a few hours, & focus on this section

that's still a problem all winter. The rain gutters are a big mistake here in

an urban area, where building zones are not correct for AK geography..

[A hot fire would melt the ice OK, but might be structurally problematic.]

Sorry to not have much newer information beyond what's already said.

Thanks for the idea, K: tried on another external SSD and same thing.

I wiped the ssd again, and ran a time machine backup on my friends almost identical mac - and it worked flawlessly. The only difference between the two machines is that he is running 13.2 and I am running 13.2.1

Suspect the issue is with 13.2.1

thoughts?

sounds frosty! Appreciate your time.

The drive was set up by Time Machine (apfs - I have tried encrypted and non-encrypted). The key piece is that the same drive used the same way on literally the exact same machine (a buddy bought his the same day as me same specs) did produce flawless TM functionality, the only difference being that his rig is running 13.2 and mine is running 13.2.1

To be clear, when I take this drive and walk over to his computer, let time machine reformat it the same way, and do a backup, it works fine. Take it back to mine, same steps, backup is slow and eventually stops somewhere in the 57-65% range and never completes the backup.

thanks for your advice regardless! Much appreciated

once again there seems to be a problem with right of access ... I would not spent time in trying to resolve the problem. I think we have two options:

i. Waiting for Ventura 13.2.2 (hopefully)

ii. switch back ti 13.1.x

Cut your time and frustation cost and just get a Crucial X8 portable SSD (1050 MB/s) formatted to APFS which is what I use exclusively for TM backups on macOS 11.7.4/12.6.3/13.2.1. There is a $10 - $40 sale on these drives thru Mar 11. I am using these

There have been years of people reporting issues with Samsung T5 and T7 drives which means it cannot just be you, and hence my first paragraph recommendation.

Now with Ventura 13.3.0 my MacBook i7 was able to backup with TM, but my MacBook pro M1 not.

I shut down the MacBook pro and my NAS, after restarting the NAS (and its server) the MacBook pro was able to connect and made TM backup with ease ...

Thanks for the advice. Apple engineer support had me exclude address book from the TM backups and that has TM functioning well. Except my address book isn't backed up...
