The most obvious possibility is that your /tmp/tarsnap/ is, well, on a temporary file system. The 'sequence number mismatch' error means that the state of the cache directory does not match the state on the server side, and if /tmp/ is getting cleaned up (e.g., when you reboot) that would explain it. If it's not that, are you sure that the some keys aren't being used anywhere else? -- Colin Percival Security Officer Emeritus, FreeBSD | The power to serve Founder, Tarsnap | www.tarsnap.com | Online backups for the truly paranoid
