Duplicati Warning - BackendQuotaNear

I am getting the following error since today, I think I updated:

2024-12-03 15:22:58 +01 - [Warning-Duplicati.Library.Main.Operation.FilelistProcessor-BackendQuotaNear]: Backend quota is close to being exceeded: Using 393.901 GB of 50.000 GB (23.500 GB available)

I am backing up my UnRaid server to a local disk. According to UnRaid, the Disk still has about 900+ GB free space. I find the message a bit odd mentioning the full capacity of “50.000 GB” when the drive has 2TB of space. Am I doing something wrong?

EDIT: I am running on Duplicati - 2.1.0.2_beta_2024-11-29

Hi @JW-CH, welcome to the forum!

Not sure why this part of the code was changed, but right now it reports the space from /, so whatever disk it “thinks” is mounted there is reported. Perhaps your OS partition is 50GiB?

I have registered an issue to fix the quota reporting.

For a workaround, you can set the advanced option to disable the warning:

--quota-disable=true

I am running Duplicati on UnRaid as mentioned. The docker.img is 50GB as far as I can remember. This might be it. Thank you for your reply and for raising an issue on GitHub. I’ll leave it as is for now and will wait for a fix. Thank you :slight_smile:

I was getting the same error as @kenkendk for a few days and thought I better look into it! I have 1.5TB free on the backup target, so was confused with the error! Good to see that it is just a bug and should be sorted soon. Thanks for this post!

I have observed this warning as well. I, too, am glad for the upcoming fix.

It’s out now in Canary test form. Maybe you refer to Beta? I don’t know that schedule.

That’s what original issue report here was on. What older release did you use before?

Regardless, I’m glad you’re happy with current behavior.

I made a mistake. I have the error on the unRAID instance and NOT on the Windows machine. I need to document more carefully. I will try the --quota-disable=true workaround on unRAID now. My deepest apologies.

–zip-compression-method=Deflate
–zip-compression-level=9
–quota-disable=true

and I am getting the warning is gone.

Despite the reported success here, that’s seemingly not working per report at

Incorrect Free Space Warnings

The help text definition of the total effect is not enough, but until recently it did:

but 2.0.9.109 removed QuotaDisable check, and I’m not sure it got relocated.

There was apparently two places the quota check was done, and I only managed to disable one. The other is now fixed:

Has this been fixed now, as I am still getting the error. I wonder if the update hasn’t hit unraid yet.
I am running ‘Duplicati - 2.1.0.2_beta_2024-11-29’

It has been fixed, but no new beta build is out, so you need to use the canary build to get the fix. A new beta build is pending a recreate error fix, but very close.

Thanks for replying. OK that’s great thanks for that.
