Things were getting pretty sluggish. So I looked at Activity Monitor and noticed that process backupd was using 78 GB of memory!!!
Closed Firefox with many tabs.
Changed to a different disk.
Rebooted.
None of that worked.
What can it be?
See attached screenshot.
macOS 10.14.6
iMac Line (2012 and Later)
I listed the way to list the local backups & delete them...
Start Terminal from spotlight.
At the terminal type tmutil listlocalsnapshotdates.
Hit enter.
Before TM writes anything to the Backup Drive it writes a local ** to your boot drive!
Thanks.
I've been at 500 GB available before and not had this problem.
As it is now, I can't do backups to any external drive. I have to abort them or its red MP city.
I have a 6 TB and a 10 TB drive for TM backups. The 10 TB still has a little room left. Actually, about 2 TB, I think.
BTW, I also ran First Aid on both external drives. Hmm. Maybe I should run it on the system drive! Won't that lock up my system for a while?
Fortunately I'm running Backblaze, so I'm still being backed up, but restores are less convenient.
"Looks like at least one local backup was skipped, I'd consider removing at least the skipped local ones.."
If a local snapshot/backup/whatever was skipped, how can you remove it, as it wouldn't exist?
afe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.
Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.
To find out if it's system wide or user specific, try this...
Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
Does it work in the new account?
Directory (computing)
From Wikipedia, the free encyclopedia
In computing, a directory is a file system cataloging structure which contains references to other computer files, and possibly other directories. On many computers, directories are known as folders, or drawers,[1] analogous to a workbench or the traditional office filing cabinet. The name derives from books like a telephone directory that lists the phone numbers of all the people living in a certain area.
Yes, I know what a directory/folder is. :-| I was once a system admin for both OpenVMS and Unix/Linux. I was asking if you meant anything particular by the phrase "Disk Directory" (your capitalization). Which directory? Is this some Mac-only term? Is there some special "Disk Directory"? The root directory? Or something like the MFD (master file directory) in OpenVMS? Many of my Final Cut libraries have 5000 folders/directories/whatever's. (No wonder it takes so long to copy one!) MG, that means that 100 libraries of that size collectively have half a million directories!) Please clarify what you meant by "Disk Directory"? (^_^)
$ ls -lR TGR_6.fcpbundle | grep ^d | wc
5075 46498 424595
$ find TGR_6.fcpbundle/ -ls | grep drw | wc
5077 74006 947029
Is this right? 5075 or 5077 "folders" in a single FCP library?
How much free space on your boot drive?
Available space: 501 GB 30.76 purgeable
Total: 3.12 TB
Fusion disk
Great news my friend... my 1st guess since it took so long, is that Disk Directory was corrupted pretty severely.
Disk Directory? Is that some specific term?
Oh, sorry for any confusion & the caps, well I was kicked out of 7th grade Language Arts!
Just meant the regular directory.
Your figures are likely correct, I don't have FCP to check.
Thanks...

Purging local backups
Please note that although this doesn't affect your remote backup from Time Machine, this will get rid of the redundancy (at least until the next Time Machine backup) that a local backup disk will provide. If you need such redundancy or are worried about the recovery of your data then you would be best served to let macOS determine when to purge these files.
Start Terminal from spotlight.
At the terminal type tmutil listlocalsnapshotdates.
Hit enter.
Here, you'll now see a list of all of the locally stored Time Machine backup snapshots stored on your disk.
Next you can remove the snapshots based on their date. I prefer to delete them one at at time. Once my "System" disk usage is at an acceptable level, I stop deleting but you can delete all of them if you want to reclaim all of the disk space.
Back at the terminal, type tmutil deletelocalsnapshots YYYY-MM-DD-HHMMSS , where will be one of the dates from your backup. This will be in the form of xxx-yy-zz-abcdef. Try to start with the oldest snapshot.
Hit enter.
Repeat for as many snapshot dates as required

tmutil deletelocalsnapshots / # deletes all the snapshots

Bothers me also, I\d incest in a new larger TM Drive.
Booted into safe mode. Memory leak plugged. Took a long time. I think it was somewhere between 40 and 60 min.
Then I did a regular boot. Seems to be working -- the memory leak is gone -- but Preparing backup... still took a long time, I'm hoping just due to catching up.
I deleted 6 out of 9 local snapshots. Made next to zero difference in disk usage. The problem remains. Is there anything else we can try?
Good to hear so far! :)
Yep, it's working now. I guess the Safe Boot must have fixed it somehow.
Any idea what happened?
Thanks!
Time Machine - backupd process memory use increases without end
