Can't copy to Seagate backup plus hub from another Seagate back up

I can't drag and drop files from my old Seagate external drive to my new one to copy. I have successfully used the new drive for Time Machine, but can't copy files on external drive.

Cloning an external hard drive to another on Mac An IT support person told me to click and drag the contents of the external hard drive I want to copy over to the newly formatted external drive. Then, I found the below answer in this community: If you need to clone Drive A to Drive B: Clone using Restore Option of Disk Utility 1. Open Disk Utility in the Utilities folder. 2. Select the destination volume from the left side list. 3. Click on the Restore tab in the DU main window. 4. Select the destination volume from the left side list and drag it to the Destination entry field. 5. Select the source volume from the left side list and drag it to the Source entry field. 6. Double-check you got it right, then click on the Restore button. Destination means Drive B. Source means Drive A. It's old, and no one has replied to the thread for a long time, hence I'm posting this. I don't know which one is correct. Could anyone help me please?! Thanks. 🙏

Cannot access Time Machine backups When I click on Time Machine on the top menu bar, it shows: “Latest Backup to “DS420plus.local: December 14, 2022” When I go to Time Machine > Browse Time Machine Backups, the only backup it shows is for 2022-12-14 and it shows only this: Macintosh HD > Volumes > com.apple.TimeMachine.localsnapshots > Backups.backupdb > Curt’s MacBook Pro > 2022-12-14-082841 > Macintosh HD - Data If I double-click “Macintosh HD - Data” to open it, there’s nothing inside it. What happened to my backups? I back up to my NAS. I went to my NAS > Time Machine > Curt’s MacBook Pro.sparsebundle. It shows “2022-12-14” as the Modified Date for these folders: band mapped The band folder is 570 GB in size. The mapped folder is 17 MB in size. When I open the “band” folder, it has 8523 items, starting with a file with name “0” and Modified Date of 2022-02-03. The last file has Modified Date of 2022-12-23. Before this, there are files with Modified Dates of 2022-12-14. So, it looks like “Curt’s MacBook Pro.sparsebundle” has my multiple backups. But how come I cannot access them with Time Machine on the Mac?

All Time Machine backups take too long 2018 Mac mini running macOS 12.6.1. I have an 8TB USB drive connected to the machine with two volumes on APFS. One volume I use to Time Machine backup my laptop over the network, and that seems to work just fine. The other volume is a local Time Machine volume for the mini. This is a fairly new disk and it was all working fine for a couple of weeks, but now the local backup takes forever and seems to find hundreds of thousands of files to backup. It takes over 24 hours to complete. Then the next time Time Machine starts, it all happens again, hundreds of thousands of changes found and it runs for 24+ hours. It's almost like the mini doesn't recognize that it only has to do an incremental backup. I know for sure there aren't all that many changes between each backup run. I've double checked the Excludes From Backup options and that all looks reasonable (it excludes both the local and remote TM volumes, iCloud, OneDrive, and Dropbox folders). I can't find anything else that would include so much changes. It estimates the size of a full backup at 1.68TB which appears to be the entire Macintosh HD (303.64GB available of 2TB). I can't find any other settings that would cause TM to do a full backup every single time and I've rebooted the machine at least once to see if that fixes the problem, to no avail. I can't upgrade this machine to Ventura yet due to compatibility issues. Any ideas what's going on or what to look for?

If you setup the new TM drive under Big Sur it will be formatted APFS, Case sensitive, and you'll have only read privileges. That's the nature of the beast. TM drives must be used only for Time Machine back-ups.

Hello, kerry179.

Your inability to drag files from one external drive to the other may be a permissions issue. It sounds like the new HD is write protected. Are you presented with any info or error message when the files won't copy?

Also, I must warn you that it's never a good idea to use the Time Machine back up drive for storing other files. It's a recipe for disaster. Time Machine is sensitive to file mishandling via the Finder.
