[Koha] File permissions for 'koha-dump' backup files

Thanks for the response, Robin. What I'm ultimately trying to accomplish is to write a small shell script that will take the daily 'koha-dump' pair of files, 'scp' copy them to a 2nd server and then 'ssh' over to that server and perform a 'koha-restore' to keep a "backup" environment in sync once per day. I'd prefer to do this as the 'koha' user instead of doing it as 'root', but currently 'root' is the only account with enough permissions to read both of the files to be copied. As you've suggested, I could simply add a 'chmod' command to root's crontab.
Maybe there's a better way you or someone else can think of to accomplish the synchronizing of a 2nd environment that I'm trying to do???

I'm going to start by asking "What is it you are actually trying to do?", as there may be another way to achieve whatever it is you're trying to do.
Now for some detail...
So, it's not _quite_ how you describe. There are two types of files here, one is the SQL and the other is the configs and so on. The SQL is group readable, the configs .tar.gz isn't. Having the SQL as user readable is to allow the feature for superlibrarians to be able download database dumps (good in a hosted environment, for example.)
The simplest way to do what you're asking would be to put a chmod/chown in the cron.daily/koha-common file that sets the file permissions to be what it is that you want after the backup process has run. That would probably be what I would do.
