apple Time Machine not working properly
I am running Big Sur and I backup (almost) every day.
If I let TM backup every hour, there is no problem but sometimes I take my MBP to an office and
when I want to backup after one or two days, it got stuck at "preparing backup"
Sometimes I have to delete one or even two backups before it is starting.
Annoying.
Could anyone please advise?
