You use the bart create command to take a file-level snapshot of a system at a particular time. The output is a catalog of files and file attributes called a manifest. The manifest lists information about all the files or specific files on a system. It contains information about attributes of files, which can include some uniquely identifying information, such as an MD5 checksum. For more information about the MD5 checksum, see the md5(3EXT) man page. A manifest can be stored and transferred between client and server systems.
BART does not cross file system boundaries, with the exception of file systems of the same type. This constraint makes the output of the bart create command more predictable. For example, without arguments, the bart create command catalogs all file systems under the root (/) directory. However, no NFS or TMPFS file systems or mounted CD-ROMs would be cataloged. When creating a manifest, do not attempt to audit file systems on a network. Note that using BART to monitor networked file systems can consume large resources to generate manifests that will have little value.
For more information about BART manifests, see BART Manifest File Format.
