I'm cleaning up the 8.2 release notes and filling in the Backup and
Restore feature description (its #3 on the list of major new features in
I'm still not clear about three areas:
1 - Does the backup attempt every 30 minutes and run successfully no
more than 1 per 24 hours? (there's mention of cron job but its not clear
to me if its in or not)? Is this turned on by default in 8.2 and is
there anyway to turn it off (pretty sure that's a default is on and you
can't turn it off but wanted to check one last time)? What happens if
there is no school server? What happens if there is a school server
listed in the networks control panel but its unreachable? What happens
if you are not registered will it still try to backup (maybe just open
and close every 30 minutes)?
2 - Does it backup everything in the journal? I think the answer last
time I asked was "everything in the datastore" which I believe =
journal, but wanted to check one last time.
3 - What is the quota and can it be changed? What is the maximum
snapshot age and can it be changed? Also, I don't fully understand what
Here's an example:
day 1 it backs up my journal which has 100 items
day 2 it backs up again and I have 5 new items.
day 3 it backs up again and I have 10 more items, but now I exceeded my
quota so it goes and deletes the old snapshot.
Does that mean it removes the first 100 items I had in the journal from
the backup? If not what does it remove?
4 - If you restore a single item, does it get placed in the journal back
where it originally came from or is it moved to the top? In either case
does it overwrite the previous instance if it still exists? Should be OK
to overwrite as I think they should be the same file, just want to be
sure I understand.
I apologize if I asked all this before. I think the last time was before
the feature was complete. I want to get it right for the documentation.
Feel free to update this
with the answers or you reply to me I'll update it then ask for a final ack.
FYI I wasn't always such a documentation pest :-( Somehow that's been my
role on this list lately, but in the past I was more interested in
designing workflow and SW.
If you want to see some hardcore documentation see the manual for one of
my previous products (a CDN)
Replication Status section seems tangentially related to this XS
Not the prettiest interface I ever worked on. You would not believe how
many hours we debated before we reached agreement on when to set those
little lights to Red, Green or Yellow! On the upside we built a system
that managed files, configurations and interbox communication on up to
2,000 servers. Last I heard, there's a content engine in every school in
Scotland, Catalonia Spain, Broward county, FL and others not to mention
every Citibank, Costco, Walmart, St George's Bank branch etc.
