Re: BRMS Backup Strategy and Implementation



fixed

You, Rob? Not follow a recommendation? :)

Yes, it is recommended to store the .nlo's outside of the data directory.
Also, when deciding on the minimum file size for DAOS always error on the
side of going too big rather than too small. It is a quick and easy
change to go smaller later on. It is painful to go the other way. Also,
the more files you have in the IFS the slower it will be for backup and
recovery. Best advice - you want to be talking thousands of .nlo files
not millions of .nlo files. Once you get 2 million .nlos for a single
Domino partition performance goes away real fast and not just for BRMS.

Good points Amy.
Not that I've been known to follow any recommendations but isn't it also
recommended to store .nlo's somewhere else also?

Hi Laura,

It looks like most of your questions were answered. I'll just add a
few
thoughts about BRMS and Domino. I would say most people started
switching
to using BRMS to back up their Domino servers about 10 years ago. It
does
a nice job and if you implement incremental saves you can even get
point
in time recovery for your Domino .nsf files. Setting up incremental
BRMS
saves is rather tricky so if you want to go that route I'd be happy to
give you some additional advice or documentation that would help. (The
rule of thumb for simple point in time backups and recovery - save the
server twice each night - incremental first, then a full).

A few thoughts about backing up Domino online:

It is very nice that you don't have to bring your server down. However;
It does not save everything. BRMS online saves will save .ns*, .nt*,
.box
and .nlo files (if you have implemented DAOS and have a recent BRMS and
Domino level). What is it not saving? the basic config files that
shouldn't change on a regular basis (notes.ini, server.id, ssl cert,
etc).
On my systems I take the servers down and do a full save of the data
directory before each Domino upgrade in addition to a year end save.
Other than that, I do not worry about saving the other files because
they
should not be changing.

A word of caution that can save you pain that many have experienced: Do
not ever end a BRMS Domino save using the ENDJOB command. It will
crash
the Domino server it is currently saving.

Where people run into the most trouble with BRMS and Domino is saves
that
touch files that Domino doesn't want you to be locking while it is up
and
running. Not saving the Domino data directory (other than in a control
group with the SAVDOMBRM command) is obvious. What isn't so obvious is
some of the other IFS directories. Here is the list of files and
directories you want to be sure to save are not attempted to be saved
while the server is running:

/tmp (note that /tmp does not = /tmp/*. Omitting /tmp/* will not
work
as the directory itself should be omitted)
/qibm/proddata/lotus
/qibm/userdata/lotus
directory containing transaction logs if they are not under the
server's
data directory
directory containing view indexes if you are building and storing
indexes
outside of the server's data directory

There is a data area available to help you avoid this so reference
[1][2]http://www-01.ibm.com/support/docview.wss?uid=swg21404738 if you
have
questions and remember that *LNKOMTLTS is your friend.

Good luck with your BRMS configuration!

Thank you to everyone who gave me some insight in how you are using
BRMS.

I am wondering if most people using BRMS are taking advantage of the
save
while active and the Lotus Domino feature save while active ?

Does anymore have any pros and cons to using either ? Any things to
watch
out for or issues in restoring ?

We are doing our yearly DR test next month which we have proven
successful
in the past, but next year the plan for our DR test is to restore using
BRMS so will be a whole new ball game ......

Thanks again

Laura

This pretty much sums up our experience as well. I would heartily
endorse the idea of taking Rob's leap of faith in trusting BRMS and
getting rid of any kind of tape naming convention.
