Is there a way to achieve tmutil behavior like it was before Big Sur? I want to manage the number of my backups manually and not wait until my back-up drive is full, because my backup storage is used for several backups, not sorely for mac.
MacBook Pro 15″, macOS 11.1
Since Time Machine on Big Sur is substantially different from previous versions, using snapshots extensively and requiring APFS on an SSD, it would seem difficult to share a disk with other systems. I would set aside your existing Time Machine dataset, in case you ever need to revert and for historical purposes. Start a new SSD disk, format it APFS and then select encryption in Time Machine preferences. It will reformat itself APFS Case Sensitive Encrypted. I don't use automatic hourly backups, but it may have a value for commercial or other reasons.

That's not really relevant to my question. I already discarded old backups, enabled the encryption and reformatted my network drive.
The question is how can I remove my new backups:
# sudo tmutil listbackups
2020-11-24-164518.backup
2020-12-17-133531.backup
# sudo tmutil destinationinfo
====================================================
Name : macbackup
Kind : Network
Mount Point : /Volumes/macbackup
ID : B6EFBCD9-AA30-404D-A530-01BE0B3BE8D2
# sudo tmutil delete -d /Volumes/macbackup -t 2020-11-24-164518
(null): No such file or directory (error 2)
# sudo tmutil delete 2020-11-24-164518.backup
Total deleted: Zero KB
Perhaps delete the snapshots?
tmutil listlocalsnapshots /
tmutil deletelocalsnapshots /
listlocalsnapshots returns an empty list
