FEATURES Important features include:
To access a snapshot, one would connect to a running fossil instance (“mount” it) and change directory to the desired snapshot, e.g. ''/snapshot/yyyy/mmdd/hhmm'' (with ''yyyy'', ''mm'', ''dd'', ''hh'', ''mm'' meaning year, month, day, hour, minute). To access an archive (permanent snapshot), a Directory of the form ''/archive/yyyy/mmdds'' (with ''yyyy'', ''mm'', ''dd'', ''s'' meaning year, month, day, sequence number) would be used. Plan 9 allows modifying the Namespace in advanced ways, like ''redirecting'' one path to another path (e.g. ''/bin/ls'' to ''/archive/2005/1012/bin/ls''). This significantly eases working with old versions of files. HISTORY Fossil was designed and implemented by Sean Quinlan , Jim McKie and Russ Cox at Bell Labs and added to the Plan 9 distribution at the end of 2002. It became the default file system in 2003, replacing Kfs and the previous Plan 9 archival file system, dubbed ''The Plan 9 File Server'', or " Fs ". Fs is also an archival file system which originally was designed to store data on a WORM optical disc system. The permanent storage for fossil is provided by Venti, which typically stores data on hard drives, which have much lower access times than optical discs. SEE ALSO EXTERNAL LINKS
