Appendix C Tape Format
Backup Professional does not use any special formats or proprietary schemes. All data is recorded in TAR (Tape Archival/Retrieval) format. However, Backup Professional does not use the tar command. The layout of a tape is described in the table below.
TABLE 30. Tape fileset layout Tape Label FileSet Label First Backup Set FileSet Label Second Backup Set xxxxxxxxx xxxxxxxxxx x...x...x...x... xxxxxxxxxxx x...x...x...x... Each section/filemark begins a TAR archive. The Tape Label is a file in TAR format that allows Backup Professional to identify the tape. Data following the Tape Label are fileset/backupset pairs that contain the data archived from a backup.
Tapes can be transported to any site and read by standard TAR utilities. Backup Professional has a utility "import" that will take a tape from one Backup Professional site and import the contents into another Backup Professional site's database, so that it becomes part of the new site's library of available backups.
