Global Cache Dir Required?

[Mark McGranaghan <mmcgrana@gmail.com>]

Hi,

Do all users of tarsnap for a particular tarsnap account effectively
have to share the same cache dir? For example, I usually use tarsnap
like `tarsnap -c -f archive-name-$timestamp archive-dir` which then
uses /usr/local/tarsnap-cache. I wanted to archive a different dir
without touching my usual cache, so I tried `tarsnap -c -f
other-archive-name-$timestamp other-archive-dir` but got:

tarsnap: Sequence number mismatch: Run --fsck
tarsnap: Error creating new archive

This happens whether or not I `mkdir other-archive-dir` before
invoking tarsnap. Am I doing something wrong here or is this a matter
of tarsnap's design? Is there any way to operate tarsnap without using
a cache dir at all?

Thanks,
Mark
