[Opensim-users] How to set up autobackup

I'm not sure which of my previous comments you are replying to here, but I
do believe you are mistaking the meaning of "compiled binary script code"
with "executable, Operating System level code/scripts".

The former ("compiled binary script code"), refers to precompiled LSL
scripts. The clue is in " ;; Allow compiled script binary code to cross
region boundaries. - ;; If you set this to "true", any region that can
teleport to you can[...]". Yes, there is a risk associated with enabling
this feature, but it has NOTHING to do with what we were discussing
earlier. This refers to scripts which are run from within rezzed/worn
objects in-world, and whose origin and intent you might not have any
control over if they are brought in by griefers. These could indeed harm
your server, but they are not related to the  "AutoBackupScript" feature of
AutoBackup. This is indeed an executable (script or binary) which only you,
as the simulator admin, have control over and which you should test and
debug before you roll it out into production. Common sense would dictate
that everyone exercises discretion when introducing foreign binaries into
any kind of server indeed, but the more adventurous among us might want to
use shell scripts which are easy to audit for malicious behaviour, or if a
compiled solution is needed/chosen, best practice would be to compile the
source code locally, both for auditing and to allow for customisation of
the code to your specific needs.

The fact remains, after all this, that you are in error trying to force
Autobackup to accept a command-script style text file as an AutoBackupScript,
since that is not the intended purpose of the parameter.

I hope this helps,
