I updated to Mojave a few weeks ago. I was able to take a full backup through Time Machine, which took three days to complete, but since then have not captured a single backup. TM never gets past the "Preparing Backup" stage. I tried deleting the .Inprocess file per an article I read on another forum, but the problem persists. I am going on 2 weeks without backup and am not comfortable with that.
Suggestions??
MacBook Pro 13", macOS 10.14
I had a similar issue. TM would only create local snapshots and not full backups to the drive.
Upgrading to 10.14.5, erasing the TM drive and starting over from scratch fixed the problem for me.
Did you erase the drive as you mentioned? On the chance that its might be the drive do you have another EHD that you can use to see if TM can complete a backup on it?
You should really have at least two forms of backup anyway, so an additional weekly Carbon Copy Cloned disk stored in another location (like in the basement) would put your mind at rest in these cases.
I just reformatted my TM drive when it gave me conflicting spare space data I didnt trust.
Thanks. I'm on 10.14.5 now.
I've been considering wiping the backup drive (Lacie) and restarting the process.
I have nothing to lose I guess. I'll start that today.
As soon as I am able to get one backup, I will worry about getting a second.
I'm still having problems with freshly reformatted Lacie. TM just churns away without any apparent progress at all.
Time Machine not working since Mojave Update
