I have VPS I used rsync to backup of my full server on a remote space. I ran the command ;
rsync -avz --exclude=/proc -e ssh / my-backup-server-address
While running rsync job, many system files were ignored due to Permission Errors and I got many errors such as ;
rsync: send_files failed to open "/sys/devices/pci0000:00/0000:00:1d.3/usb5/5-0:1.0/usbdev5.1_ep81/uevent": Permission denied (13)
rsync: read errors mapping "/sys/class/net/lo/statistics/multicast": No data available (61)
WARNING: sys/class/net/lo/statistics/rx_bytes failed verification -- update discarded (will try again).
How can I fix this?
