I stopped and resumed MA 3 times. Each time the estimated space was less than the previous time. It looks as if MA does indeed store partially transferred data somewhere and then puts it all together in the end, or something to that effect.
The first thing I would do is Clear History from the Safari menu. After that quit and re-launch Safari while holding down the Shift key. That will launch Safari in Safe Mode and disable any third party extensions.
If Safari behaves itself after that, disable your extensions and re-enable them one at a time.
Failing that, more extreme measures are in order. ...
No - you don't need to have two copies of the files you backed up.
I think it's a good idea to restore all the files you want to have a backup copy of, however. Spotlight search will let you read / search all the files, but you have no safeguard for when the backup disk dies or fails, so your retention policy for everything you don't copy back is until that ...
I think the Energy Saver suggestion is a good place to start:
» System Preferences » Energy Saver » Schedule and set it for, say, 30 minutes before you want to leave for work.
However, I would not schedule it to go back to sleep unless you know that it has actually succeeded in ejecting the disk. Otherwise you might have the disk not eject for some ...
You can schedule your MacBook to wake before your scheduled disk eject job and then go back to sleep afterward (something like wake up at 5:00, sleep at 5:05 and your eject job in the middle).
from Apple support :
From the Apple menu, choose System Preferences, then click Energy Saver.
Click the Schedule button, then use the checkboxes and pop-up menus to ...
"A few times a year I back up pretty much everything to that."
I suggest you use a cloning software package for making your once in awhile copies.
I use Time Machine to get a historic copies of my files and a cloning software package to get a bootable clone of my Startup Disk.
Carbon Copy Cloner will copy your Startup Disk to an external FireWire drive....
I agree that TimeMachine will backup both internal volumes.
My sister's 2012 MacBook is running terribly slow
I would spend a little time diagnosing why the machine is running slow.
Run activity monitor /Applications/Utilities/Activity Monitor. Check ram usage and paging.
Run etrecheck https://itunes.apple.com/...
AFAIK there is no option to limit backup size on the client (macOS) side of things. For server-side limits two options come to mind:
create individual partitions for each Mac to be backed up and size accordingly (on Macs you could also use sparseimages but I don‘t know whether these are available in your setup)
create individual users on the server for each ...
In this situation, renaming files is not the way to go!
As you stated in the OP, "There's almost 500,000 files, so doing this manually is not practical.", and as mention in my comment to the OP "I'd recommend checking out Gemini 2 which you can download a copy for free and run it to see what it finds. If you like the results you can consider purchasing it."....
Here is a solution that I have tested several times and it seems to work. I'm sure someone with more experience can offer a solution which is much quicker than mine, but so far this is the best I can come up with.
I strongly suggest making a copy of your "recovered" files with generic file naming. Then I would run the following code on your copied files. ...
I would strongly recommend a total backup of all your data before proceeding. After that, create a new account and play-around from the new account.
"Advanced Bash-Scripting Guide" covers everything with numerous examples. http://www.tldp.org/guides.html It the fist manual listed. Bash is powerful but exacting.

I think I have the same problem today. I resolved my problem by rebooting to macOS Recovery (turn off your Mac and press ⌘+R during while pressing power button), and use disk utility to check(First Aid) my boot drive.
I had the exact same issue using a combination of ZFS Samba, could create files on the mounted drive when testing but trying to create sparsebundles failed.
Turns out as others have pointed out that it might have to do with filesystems used, I had to add vfs objects = catia fruit streams_xattr zfsacl for it to work.
I had the same problem and found the solution at https://discussions.apple.com/thread/8597674:
Add your Terminal app (i.e. Terminal.app or iTerm.app) to your list of apps for full disk access in Settings > Security & Privacy > Privacy > Full Disk Access.
I was able to solve the problem myself, in few super easy steps, here's how:
-Right click on user1.sparsebundle -> get info, then make sure your user has the permission to open it
(if not then click on the lock at lower right of "user1.sparsebundle" info window enter your password and add the user you want it to be shared with.)
-hook up a new ...
I have been able to repair this. It may have been luck. What I did:
Copy all private/var/db/openldap/authdata from all Time Machine
backups to a working directory (for i in 2019*; do ditto $i/DumbledoreRoot/private/var/db/openldap/authdata/ /tmp/$i/authdata; done). My boot volume is called DumbledoreRoot.
Run crash recovery on all the authdata copies, to ...
