The backup system is now as follows: - Dailies are unchanged. - Weeklies run the same rotating cycle of 5 tape sets (still marked 12-16, someday I'll rationalize the numbering) as before. - Every four weeks the ZOO tapes of the current tape set are kicked up to the second shelf as archive tapes, labelled by their date. - Every six months the rest of the tapes in the current set accompany the ZOO tapes into the archives, to provide long-range backups of the system areas. - Tapes moved into the archives are replaced by new tapes. Old backup tapes are never reused. We may periodically release old archive tapes to the "used tapes" bin. The messages put out by the full-backup program have changed slightly to reflect all this. Also, people doing backups should read the file /backup/relabelling for a couple of minor notes on tape shuffling.
