Chroniton::Backup - implements full and incremental backups
None of these subroutines are exported by default. Please load them into your namespace by specifying them on the module load line:
use Chroniton::Backup qw(backup);
Perfoms a backup of each file in @sources to a new subdirectory of $destination. If $against is specified, an incremental backup is performed by comparing the files in each of @sources to the identically named files in $against. If the files are the same, the new file in $destination is linked to the version in $against (instead of being copied from the $source).
Returns a BackupSet object. Dies on a fatal error, otherwise logs errors and warnings to $log, a
Clones $src into $dest, recursively decending into subdirectories, depth first. If $against is specified, each file in $src is compared against the file of the same name in $against via the $compare_ref subroutine. This routine should return 1 if the file from $src needs to be copied to $dest, or 0 if the file placed in $dest should be a (relative) symbolic link to the file in $against.
Returns nothing. Dies on a fatal error, otherwise logs errors and warnings to $log, a
