+tahoe backup ~ work:backups
+
+ This command performs a full versioned backup of every file and directory
+ underneath your "~" home directory, placing a read-only timestamped snapshot
+ in e.g. work:backups/Archives/2009-02-06_04:00:05Z/ (note that the timestamp
+ is in UTC, hence the "Z" suffix), and a link to the latest snapshot in
+ work:backups/Latest/ . This command will use a small SQLite database known
+ as the "backupdb", stored in ~/.tahoe/private/backupdb.sqlite, to remember
+ which local files have been backed up already, and will avoid uploading
+ files that have already been backed up. It compares timestamps and filesizes
+ when making this comparison. The "tahoe backup" command also shares
+ directories with the previous backup when nothing has changed, to run faster
+ and to reduce the number of directories created.
