Server service hangs but is running, no response in GUI. 0 space despite "Global soft filesystem quota" set 70%

Server
1

Windows 11 pro, Server v 2.5.33 (latest) client 2.5.25

PROBLEMS:

  1. Storage keeps getting full. Server is unable to delete/free up room despite proper access/rights
  2. Server is hunh (Service shows running, but no repsonse from serverr GUI. I am forced to start/stop the Urbackup Server service.
  3. Errors logged (before debug enabled)
    ERR1:
    “WARNING: Deleting MySysPathL\250512-1635_Image_C\Image_C_250512-1635.vhdz.bitmap failed. The system cannot find the file specified. (code: 2)”

Search only found this thread with 317 views and no answers. Likely was from when I tried deleting or stopping the backup?
Thread: 12117 (new user limit 2 links)

ERR2:
“2025-06-16 21:54:37: ERROR: Sending broadcast failed!
2025-06-16 21:54:37: ERROR: Sending broadcast failed! (ipv6)”
( repeats, Only soluition I saw was to disable WAN ports on windows, but hter are 8 different choices on my machine - not sure which ones are needed)

Some of my attempts:
A) weeks of researching here etc FAQ, manual.
B) Tried multipe times lowering the “Global soft filesystem quota”, currently set at 70%, (of a 7TB drive)

enabled debug, and NOTE from 2025-6-16 through 20205-06-21 I was switching internet providers and had name resolution issues, so ignore 6-16 but I iuncluded it in case these were important to see.

Log file with debug on, this link is live for 6 days

I assume you are asking how to stop the urBackup from filling the drive?

All I know is " Settings \ Server \ Global soft filesystem quota ". Mine is still default 95% in most cases. Never caused a problem. (Win10 and Linux systems as servers)

I also make sure it is backing up to a drive that only has urBackup data on it. I never share the backup target with other items.

I also haven’t changed many other values from default. Especially making sure the clean-up can run.

What kind of data do you have being backed up? Large or small files? Does it change a lot?

What has always surprised me on my setups is I rarely fine tune how many versions to keep. And yet urBackup seems to keep itself within quotas.

Running cleanup shows unexpected results:
Client with id=1 has 2 full image backups max_image_full=5
2025-06-27 11:14:51: Client with id=1 has 4 incremental image backups max_image_incr=30
2025-06-27 11:14:51: Client with id=2 has 1 full image backups max_image_full=5
2025-06-27 11:14:51: Client with id=2 has 4 incremental image backups max_image_incr=30
2025-06-27 11:14:51: Client with id=1 has 2 full file backups max_file_full=4
2025-06-27 11:14:51: Client with id=1 has 40 incremental file backups max_file_incr=80

it did not clean up the files, I did find another command (I posted new problems, I can update later with what resolved it.) -

I had the soft filesystem quota set to 50% and still space was used. It was corrupt or orphaned files I believe.

the command

urbackup_srv remove-unknown
fixed my issue.
I tried cleanup.bat prior the remove unknown, but it didnt create space.

I ran it just now and it did clean up the space.
cleanup showed a bunch of

“WARNING: Deleting E:\Backup\UrBackup2025\L\250903-1955_Image_SYSVOL\Image_SYSVOL_250903-1955.vhdxz.bitmap failed. The system cannot find the file specified. (code: 2)”

I am trying vhdx uncompressed now to see if I can mount the image afterwards.
