I don’t know if this is just a weird setup, but for whatever reason when using the LinuxServer build of Duplicati (Docker Hub) I am plagued with size check issues, not sure if it’s just not how it’s supposed to be used or if I’ve overly complicated the install, but this seems like a pretty easy setup.
Error Sample:
- 2022-03-22 22:32:43 +00 - [Warning-Duplicati.Library.Main.Operation.FilelistProcessor-MissingRemoteHash]: remote file duplicati-b644ea6d6f91a4cfbb5a8b9ff7fdd81af.dblock.zip.aes is listed as Verified with size 247463936 but should be 262133629, please verify the sha256 hash “wtrZfDMz6AAN6pPupd5qaXszuMiFk5ojEF7r0Z/PDsQ=”
Setup:
- Host: Physical
- Model: Dell R620
- OS: Debian 10 Buster
- Docker: Version 20.10.13, Build a224086
- Network Shares: CIFS
What I’ve done here is setup this physical host as an “in between” for all my network shares, some on local Windows hosts, USB mounted HDD to Router, and external NAS box connected in via VPN. I mount all the shares as CIFS due to the majority of my Source data coming in from Windows and going back out to Windows (plus others but they are all CIFS anyways).
Now I’m not sure why, maybe it’s the OS mounting CIFS as I’ve read some folks saying that Duplicati doesn’t like things like CIFS caching being enable, other issues I’ve seen are with mono version (in the container the mono version is 5.20.1.34). I really don’t know, but every backup I setup and run has these Warnings all over the logs, and they are correct, the size matches the “Verified size” and not the “should be” size, is there something with this setup that Duplicati doesn’t like?
