What in the world is Time Machine backing up???

Is CCC not usable with a NAS?

I backup terabytes of files to my NAS using CCC with no problems.

Howard Oakley seems to have a lot of in-depth info on Time Machine (among other things). A lot of it is over my head, I'm afraid, but it's here: https://eclecticlight.co/?s=time+machine

Wow a lot of useful information. Thanks!

This is great to know. So, CCC will allow me to select my network attached NAS as the backup drive?

Yes.

I see this message "The Internet Archive's sites are temporarily offline due to a planned power outage." that suggests it's a transient situation. Not sure how long "temporary" is though.

TimeTracker is a great utility that will let you browse through your TM backups and see what's changed. If you find something big that's changing a lot, you can go into the settings as people suggest and exclude that. Pinpointing what it is will help you target the exclusion more precisely.



Don't mind the "extremely early state" stuff -- I've been using this for easily 10 years if not more and it's always been "prerelease" LOL. It works fine, but give it a while on first launch to scan through stuff.

this is a wrapper around tmutil I assume

I wanted to try CCC but its website said that a network NAS backup is not recommended. I invested in an expensive 6TB NAS a last year or earlier (I don't remember when) to use for my Time Machine backups for my Macs. If I use CCC the money I spent on the NAS will be waisted. Is CCC not usable with a NAS?

Time Machine backup to NAS is much more reliable now, using APFS

Don't overthink it. Time Machine is doing exactly what it's supposed to.

How are you getting an APFS file system on your NAS?

I had to buy a new external drive for TM backup. It is only USB 2.0 but I formatted as APFS and it is so much faster it surprised me. It also un-mounts so much faster. Much better
