To simplify transfer and management of backup data, you can
keep each backup in a single file (the backup image). The
backup-to-image option performs a
backup directly to a single file, or the options here can pack
an existing backup into a single file or unpack a single-file
backup to a full backup directory structure. For usage and
examples, see Section 3.3.5, “Making a Single-File Backup”.

Unpacks a single-file backup to a full backup directory structure. You specify the paths to both the image file and the destination directory in which to unpack. For usage and examples, see Section 3.3.5, “Making a Single-File Backup”.
Packs an existing backup into a single file. Specify a
-(standard output) to stream an existing backup directory structure to a tape device or a command that transfers the backup to another server. The
--backup-imageparameter is either
-or an absolute path outside the
backup-dirdirectory. For usage and examples, see Section 3.3.5, “Making a Single-File Backup”.
Display the contents of a single-file backup. Lists all files and directories in the image. The
--src-entry=can be used to list a specific file or directory. If the name is a directory, all its files and subdirectories inside the image are recursively listed. For usage and examples, see Section 3.3.5, “Making a Single-File Backup”.
Verifies that a single-file backup is not corrupted, truncated, or otherwise damaged. This operation compares checksum values stored in the image file against the contents of the files. You might run it after transferring the image file to another system. To see the sequence of commands involved to produce and check a single-file backup, and the output for successful and unsuccessful checks, see Section C.4, “Validating a Single-File Backup Image”.
Unpacks an individual file or directory from a single-file backup. For troubleshooting or restoration operations that do not require the full set of backup data. The resulting file or directory goes in the current directory, or in
backup-dirif specified. All files and directory contents in the image with absolute path names are extracted into the same absolute path names on the local system. For usage and examples, see Section 3.3.5, “Making a Single-File Backup”.
--src-entry=option can be used for selective extraction of a single file or single directory in image. Specify the path as it appears in the image.
--dst-entry=option, along with
--src-entry=option can be used to extract a single file or single directory into a user-specified file or directory respectively. If the
--src-entryoption is used, but
--dst-entryoption is omitted, then the selected file or directory is extracted to the same path in the local file system.
The default destination for the extract is the current working directory. It can be overridden by the
--backup-diroption. All the files with relative pathnames in the image are extracted to pathnames relative to the destination directory.
If the image contains some entries with absolute pathnames, those entries are extracted to the same absolute path names even if
--backup-diroption is specified. The
--dst-entryoption must be used to relocate an absolute pathname.
