Simply after upgrading to macOS Sonoma, I’ve observed that Time Machine has been getting caught at round 96% completion on its hourly backups. It spends 10s of minutes apparently slowly studying from my remotely-attached RAID array (TrueNAS), making no reported progress, earlier than ultimately finishing the ultimate few %. It solely finally ends up copying a couple of hundred MB of information. Earlier than upgrading, it accomplished way more rapidly. I’ve verified that the pace of the TrueNAS SMB share has not modified and might simply saturate a gigabit connection.
I’ve beforehand had points with Time Machine corrupting the sparsebundle on the NAS (which I’ve repaired with fsck and subsequently verified a number of occasions), so I’m cautious of messing with it throughout an in-progress backup. So, the truth that it takes so lengthy for these incremental backups is irritating.
Console exhibits backupd repeatedly emitting the next messages each few seconds, although I do not know if that is regular and if it was doing this earlier than.
default 00:38:48.999607-0700 backupd [0x7fed94709bc0] activating connection: mach=false listener=false peer=true identify=com.apple.backupd.sandbox.xpc.peer.0x7fed94709bc0

error 00:38:48.015392-0700 backupd com.apple.backupd.sandbox.xpc: connection invalid
There are additionally some “eliminated presenter” and “eliminated supplier” messages interspersed much less continuously.
Has anybody else skilled comparable points, or have any strategies for debugging this?
