how to get time machine to work 2017 iMac ventura

[lasloduncan]

so far it has escaped me.?? --would anyone guess the time machine disk has to be larger than the 2tb internal system disk that came with the 2017 5k?-- I since have reloaded it to a one tb ext ssd and boot and run from that??--seems there are lots of problems with ventura and tm and so far lots of swing a dead car over your head hocus hocus --none of have worked for me...thank you

I'm not understanding exactly what you're getting at. What did you reload onto a 1 TB drive, the system or TM? If your internal drive is 2 TB, & is reasonably full, you can't expect 1TB to handle the backup!

I have a 2017 27" iMac in which I installed 2 x 1TB internal SSD's and have a 4TB external drive for TM. The TM drive has used 3.35TB, while the 2 internal drives have only used a total of 863 TB. It all depends how full your internal drive is and how long you want TM to keep the snapshots; no different than the earlier OS's to Ventura. I've had no issues with Ventura, so don't know why you're swinging dead cars

Yes. It should be at least 4 TB backing up a 2 TB internal drive. As above the more space you have the longer period is covered with backups. In my case I backup ~2 TB to 6 TB TM volumes which gives me close to a year of backups.

Be sure your 3-2-1 backup strategy has just one TM backup as they tend to fail.

aha as I suspected thank you very much just tried a new 2tb ssd .....no luck.......no good not having a backup will order one tomorrow 4tb should get it?? ya think? ssd? once again thank you--would you not think that timmy cook would have msg ...hey you moron you need at least double tm disk....instead of nothing...heres one .." not enough write space on your tm disk? maybe i could be an apple genius....boy talk about a misnomer (geniues)

I just did a carbon copy cloner on the 2tb ssd just in case......

So what is the problem? Need a detailed description of what you did and how it fails.
