deleted wrongly Backup files from backupdb of time machine
The folders I deleted of the Backup files from backupdb of time machine are in backup trash and trash will not empty them, so I think the backupdp is still using the files from trash. I just leave them there.
I think that because I asked the info where the files are and the info said "on my backup". It did not say in the trash of my backup disc.
When I deleted the folders in backupdb I only wanted to delete 2018 but the computer deleted also 2019 and 2020. Despite that all is well I just leave all like it is. The trash on my computer with the backup disconnected is empty, but with the backup connected , the trash is full of all the backupdb folders.
Before when I wanted to delete other small files from the trash in the backup it said it can not do this because the file is in use.
Therefore I switched the time machine automatic backup off. After that I could delete smaller folders.
Maybe I can now also delete the backup folders in trash, since I switched automatic backup off, but because it takes ages I am not trying that any more. But if you have smaller folders from the backupdb which you accidently deleted the wrong way round, you could try to delete the backupdb folder with the automatic backup switched off on time machine..
