Based on your original post, I think the reason you don't understand
Raymond's approach is because you (like most users) don't understand
what you mean when you say, "Storage Group."
A Storage Group is just a name you choose for a bunch of directories.
A directory is a location on a file system. (Most users seem to think
that a directory is a "Storage Group"--that's a directory entry within a
Storage Group, which is allowed to contain as many directory paths as
You set up your Storage Groups as:
SG Name: Default
Directories within SG:
Then, you create a Storage Group:
SG Name: Archive
Directories within SG:
etc. Then create recording rules to record to Default Storage Group and
do not ever specify Archive Storage Group in any recording rule. That
way, all record is done to the directories specified in Default Storage
Group, and no recording is done to directories specified in Archive
Then, when you want to archive, just simply move the file out of one of
the Default Storage Group directories and into any of the Archive
Storage Group directories--and all will work fine. There's no need to
tell MythTV that you moved it. It just works.
(The only constraint is that the host that recorded the video must be
able to access it in the new directory--whether the new directory is a
local directory or mounted via NFS/CIFS.)
