I have troubles backing up an LXC container on PROXMOX VE 9.
I do it as a backup job that saves shapshot images on a NAS.
Strange thing is that it happens sometimes, not always.
Traced error is:
2026-01-10 01:05:02 INFO: zstd: error 70 : Write error : cannot write block : Bad address
Backup NAS is a Synology RS422+ (OS DSM 7.3.2)
Images are saved on a mounted folder shared by the NAS as an SMB volume
Diagnostics on the NAS did not reveal any problem.
More detailed infos are attached.
Can you please help to understand?
