Use stat to get the modification timestamp of the file and store it on a variable. Compare it later to check changes. Of course the filesystem should be consistent with updates. Some filesystem may have no modification timestamp? I don't know. Perhaps.

NAME
amcheckdump - check the results of an Amanda dump SYNOPSIS
amcheckdump [--timestamp|-t timestamp] [--verbose] [-o configoption...] config DESCRIPTION
Amcheckdump verifies Amanda dump images by reading them from storage volume(s) and verifying that the images can be parsed by the appropriate application (if available). For example, a GNUTAR image is passed to GNU Tar for parsing, and any errors (e.g., corrupt or missing data) are noted. The application runs on the most recent dump or, if --timestamp is specified, on the most recent dump with that timestamp. Note that the verification is local to the Amanda server; if the dump application is not available, or is configured differently on the server than on the client, then the verification will most likely fail. If a changer is available, it is used to load the required tapes. Otherwise, the application interactively requests the tapes. See the "CONFIGURATION OVERRIDE" section in amanda(8) for information on the -o option. EXAMPLE
# check the most recent dump amcheckdump MYCONFIG # check a specific dump from back in '78 amcheckdump MYCONFIG --timestamp 19780615 SEE ALSO
