The thing is that having "low-level addressing" data in a bootstrap file allows Bacula to be blazing fast in positioning the tape to the beginning of the required backup's data. If the only thing you know the name of the file, you basically need Bacula to read all the entries from the beginning of the volume one by one until it finds the one with the matching name. That's why it would literally buy us nothing: we already have lists of files to supply `bextract` via its "-i" command-line option. Restoration in this case takes several hours for an LTO-4 drive -- spent mostly in reading the headers of the unwanted files and skipping past them. IOW proper boostrap files serve like "indexes" to the tape's data. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Bacula-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/bacula-users
