vzdump backup to s3fs

[tugdualenligne]

Just discovered this crazy thing: you can mount from Proxmox a S3-compatible object storage and backup to it using vzdump (and therefore externalize your backups instead of having them locally)

Amazing

Unfortunately, when trying to backup to a fstab mounted S3 filesystem, I get an error "cannot rename" from .dat to .zst the VM file that has been backed up, and the back fail miserably. What is NOT renamed, though, is correctly uploaded to my S3 bucket.

I tried many options in my fstab, one of the config that is working is: ml30-vm-backup /mnt/Storj_S3 fuse.s3fs _netdev,allow_other,passwd_file=/etc/passwd-s3fs,url=https://gateway.storjshare.io/ 0 0

Any idea?

FYI, I used those two nice explanations to set this up, if any one is interested:

Hi, I've deal with somwething similar a few days back. While I am still looking for a proper solution (rclone w/ s3 maybe) but I was able to do the following:
- download the .dat file
- re-upload the same file but now renamed, so now it is a .zst file.
- It shows up under "backups" in proxmox.
