Catalina & Time Machine back ups are extremely slow!!?

I know this happens during a major OS upgrade. Typically the first back up & maybe a day or 2 later Time Machine is super slow sometimes even getting stuck during "Preparing to Back up" but it's been almost 2 weeks now since the upgrade & my back ups are taking basically a full day for just ONE back up?? Sometimes when the back up is only 10mb then it takes only a 1/2 a day but anything over 25mb forget it, its' going to be until the next morning. Or sits in "Calculating time remaining" for 6-8hrs??

I've been scouring through searches & it doesn't seem like this is a major issue this upgrade around. Guess I'm the only one.

Anyone going through the same issue & is there any solutions yet?

Hi ibroker,

Thanks so much for using Apple Support Communities. It's great to have you here. I see from your post, you're noticing your Time Machine backup are taking a bit longer to complete.

If a Time Machine backup takes longer than you expect has some additional steps that may help resolve your issue.

If you continue to experience after attempting those steps, you can Contact Apple Support for additional steps.

Kindest regards.

Never mind it seemed to work for a day or 2 & now it's back to taking all day to back up once instead of hourly. How has this gone on so long without a fix yet???
