This document describes how to run backups on locally-mounted remote filesystems.

To mount or unmount a partition, you must place the partition in the /etc/fstab file. This file contains a list of mountable file systems and their configuration options. The backup utility only mounts or unmounts partitions that appear in the /etc/fstab file.


  • We strongly recommend that you do not perform backups to remote filesystems (for example, NFS, CIFS, smbfs, or other types of network drive systems). While you can store a backup directly to a remote filesystem, cPanel & WHM does not support this configuration.
  • We strongly recommend that you work with a qualified system administrator to manage this custom backup path to avoid potential risks.
  • We are not responsible for any data loss that an attempt to perform the steps in this document causes.

Configure the filesystem

If you use a mounted filesystem to store backups, we strongly recommend that you mount the system with the noexec option. To do this, open the /etc/fstab file with a text editor and edit its entry to resemble the following example:

/dev/sda5 /backup ext3 defaults,noexec 0 0

The example above describes the following configuration options:

DeviceDefault mount pointFile system typeMount optionsDump optionsfsck order

Remount a backup disk

To remount a backup disk while the system reboots, run the following command:

mount -o remount,noexec /backup
