I noticed from a report sent by the Proxmox backup routine that the backups last night failed. I looked into this and saw that the storage object for network backups had a ? badge and that this indicated that the status was unknown.
I opened the storage container configuration and noted that everything looked right. I noticed that the configuration used my account name and remembered that I’d just changed the password for it. I decided that this was not a good idea to use my account and created an account specifically for handling these jobs.
The issue was the storage object, so I took a picture of the configuration and blew away the storage object reference in Proxmox.
Since this was going to a CIFS share in a container I had to create the user account in Linux and then use “sudo smbpasswd -a <user>” to add that user to allow them access to the shares.
I recreated the storage object using the same settings with the credentials that I’d set up. If there was a problem here’s where I’d see it. It worked as intended.
Since everything looked OK I chose to manually run the backup job. I received an email message after about an hour when the backup job was done. This told me to run the second backup job that had failed to run last night.
All’s well. The lesson learned is that if you change your password there are back-end systems that this could effect, so be careful.
