tar

tar

The tar utility backs up files and directories. You can copy files to tape, create tar files, compare files on tape to files on disk, read standard input, and pipe the output of tar to other processes. This command is widely used on UNIX systems worldwide.

Note: XFS and tar: The -K option is used with the tar(1) command for files larger than 2 GB. If the -K option is not used, tar skips any files larger than 2 GB and issues a warning. Note that use of this option can create tar archives that are not usable on non-XFS systems. The -K option cannot be used with the -O option, which creates tar archives formatted in an older, pre-POSIX format.
