If the Linux OS has NFS server enabled, you can backup files from the Linux OS by mounting the NFS share to the NAS local folder, then run rsync command.

Sample steps:

Connect to QNAP NAS via SSH

run mkdir /mnt/nfsfolder to create a local mount point
Mount Linux NFS share in the NAS using the mount point, in this example, path is 10.64.72.102:/share/CACHEDEV1_DATA/nfsshare102

[/] # mount -t nfs -o rw -O user=admin,password=mypassword 10.64.72.102:/share/CACHEDEV1_DATA/nfsshare102 /mnt/nfsfolder
[/] # df
10.64.72.102:/share/CACHEDEV1_DATA/nfsshare102 297.8G 63.9G 234.0G 21% /mnt/nfsfolder
[/] # ls -l /mnt/nfsfolder/
Run the rsync command. If the destination in the NAS is Public shared folder, such as the path /share/CACHEDEV1_DATA/Public/ run the command:
[/] # rsync -avz --progress /mnt/nfsfolder/* /share/CACHEDEV1_DATA/Public/
