How To Install xfsdump on CentOS 7
Introduction
In this tutorial we learn how to install xfsdump on CentOS 7.
What is xfsdump
The xfsdump package contains xfsdump, xfsrestore and a number of other utilities for administering XFS filesystems. xfsdump examines files in a filesystem, determines which need to be backed up, and copies those files to a specified disk, tape or other storage medium. It uses XFS-specific directives for optimizing the dump of an XFS filesystem, and also knows how to backup XFS extended attributes. Backups created with xfsdump are “endian safe” and can thus be transfered between Linux machines of different architectures and also between IRIX machines. xfsrestore performs the inverse function of xfsdump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may be restored from full or partial backups.
