Backup failed with "Home dir chown failed"

JimLam

All backup failed with the same error message "Home dir chown failed". The backup is targeted onto a NFS mounted volume,

Is there any special requirements for the NFS mounted volume for backup to work?

JimLam NFS mounted volume for backup to work

They are not supported. NFS can't handle the hard links.

JimLam Is there any special requirements for the NFS mounted volume for backup to work?

What made you think that NFS could work?

JimLam

NFS does support hard links. In order to double check, I just tried it.
Please see picture here

I just unmount the NFS volume, and use the local ext4 directory, and triggered a manual backup.

Exactly the same error.

The backup server created all the websites/customers as an user in the backup server using their uuid, and then create a directory for backup.

I do a chmod 0777 for the backup directory, and rerun the backup again. This time it seems that it does do the backup, as a whole bunch of directory and files are created. However, the backup still failed with the same error.

I am not sure what the problem is now.

Can we use other backup solution such as Acronis, Veeam, Vembu or Bacula or something?

Is the backup role on the same server as the control panel? Or another server?

When you run:

ls -lha / and ls -lha /backups

What do the user, group and permission show for the /backups and /backups-subfolders?

It should be something like this:

drwxr-xr-x 21 root root 4.0K Jun 9 06:07 backups

drwxr-x--- 115 071a936985f84a0fb98f36de8279d932 071a936985f84a0fb98f36de8279d932 4.0K Jul 9 10:41 071a9369-85f8-4a0f-b98f-36de8279d932 drwxr-x--- 103 0f3bad4389ed4f909fe688f0daea4954 0f3bad4389ed4f909fe688f0daea4954 4.0K Jul 9 10:47 0f3bad43-89ed-4f90-9fe6-88f0daea4954

If not, there's ownership/permission issues, which happens a lot with NFS due to how it's built.

JimLam I do a chmod 0777 for the backup directory

Oh no......

JimLam Can we use other backup solution such as Acronis, Veeam, Vembu or Bacula or something?

Sure, if you code it up and make it work. There's the native Enhance backup way, which is the best, easiest and most efficient with the cluster. There's S3, which works but has plenty issues and downsides. The rest is up to yourself.

Stick with the built-in backup system, just use a cheap storage VPS from AlphaVPS or any provider you prefer. It’s the most efficient, cost-effective, and fastest way when restoring a single site, server, or even a full cluster. No need to complicate what’s already built for simplicity and reliability.

Thanks for all your advice. I just connect a local storage to the VM, and it works fine now.

The reason for using NFS was that storage node has a much bigger available space than the local disk. We will just add some extra space to the host and that should work fine.

Thanks again for all your help.
