Archive Compression

KBackup will compress the files stored if you activate this in the profile settings. Depending on the availability on your system it chooses xz, bzip2 or gzip compression. KBackup will compress every single file and store all files with an added file extension (.xz, .bzip2 or .gz) into the then not-compressed .tar archive.

When you have selected to create the backup on some local filesystem (e.g. your extra disc, ZIP drive, etc.) - which means you did not enter a remote target URL - KBackup might split the whole backup into several archive slices due to media capacity limitations.
