Linux Learning RHEL7 XFS Backup and recovery

The RHEL7 file system is updated to XFS. XFS provides Xfsdump and Xfsrestore tools to assist in backing up data from XFS file systems. Xfsdump back up an XFS file system in Inode order. Unlike traditional UNIX file systems, XFS does not need to be unloaded before dump, and a dump of the in-use XFS file system can guarantee the consistency of the image. Unlike XFS's implementation of snapshots, the process of the dump and restore of XFS can be interrupted and then resumed without the need to freeze the file system. Xfsdump even provides high-performance multi-threaded backup operations It splits a dump into multiple streams, each of which can be sent to a different destination.
