How to Run Backups on Locally-Mounted Remote Filesystems
Last modified: July 30, 2019
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
- 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.

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

/dev/sda5— The device.
/backup— The default mount point.
ext3— The file system type.
defaults,noexec— The mount options.
0— The dump options.
Remount a backup disk
To remount a backup disk while the system reboots, run the following command:
mount -o remount,noexec /backup
