Time machine error on QNAP NAS after upgrading to Monterey from Big Sur "the backup disk image could not be created"

I use a QNAP for backups. After upgrading from Big Sur to Monterey, can no longer make backups. Perhaps its new file system requirement. If not fixable, what us procedure for deleting old backups from NAS and starting over?

Thanks

Mac mini 2018 or later

Time Machine error 19 I'm using Time Machine to backup to a WD and getting "MacBook Air 2021.sparsebundle” could not be accessed (error 19)". MacOS Ventura 13.1. All my old backups are gone and now unable to create a new backup. Any thoughts? 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?

Hello Twinton,

While QNAP is from a third-party, we've found the following thread that came directly from QNAP: How to delete time machine backup image to free up space. If this does n't help with deleting your old backups, we'd recommend connecting with them directly: QNAP Customer Service.

Best!
