Hi Anton,
Thank you. But, It is not about how to optimize and tune your network to get better backup performance.
In my case, we are trying to reduce the value of the data. We do the file level backup every night over Gig networks and it completes within 6 hours for 500Gb. But, when you do it for Domino, it is every time a full system backup, even if you try to do incremental backups. Every time all nsf files have changed. If you have the transaction log enabled on Domino, then using NetBackup add-on/advanced client for Domino, then you can run incremental backups against the transaction log. My question was, if anybody does backups using transaction logs for Domino. Also, we are going to skip Domino version 7.x and go directly to Domino 8.0. Per Symantec, no support in Netbackup with teh advanced client for Domino 8.0. Many companies are going to skip 7, and go straight to 8. So, how Symantec/Veritas is going to address this? Actually, we are going to test the transaction log and NetBackup advanced feature for Domino on the existing 6.5.4 version, and see how it performs.
If I would not meet the backup window, then I would start looking on tuning my network, servers, convert the client to the SAN media server, and so on.
Thank you,
Boris

We have installed dedicated GbE network card into Domino server and take
advantage of multistream backup by using NEW_STREAM directive. Every stream
goes to its respective tape drive. So overall backup spead is about 50-60
Mb/s. Network card utilization is about 80%. That looks great!

We have several Domino servers and have been able to utilise point
in time restores.
Our win2k3 mail server backs up 350GB at 10-12MB/sec using the notes
agent. Doing an off-line backup we are able to do 25-30MB/Sec
We are hoping to move our mail server in the new year back to
Solaris. We hopefully should see 25-30MB/sec backup times.
We still do nightly FULLS and have touched lightly on daily notes
transaction only backups. They seem to work fine.
Our notes admin will be implementing a notes archive server before
year end. The hope is that our daily mail backup volume will
decrease and that we can move data to the archive server on a
quarterly basis. The archive server will be backed up quarterly
while the email server will be backed up daily. I don't think we
will be using veritas Vault.

We use the notes agent, and write about 380GB of data to tape, coming
from two servers. The mailboxes are split by alphabet. Average
throughput to tape is about 8 to 10 MB/sec from each client, and we do
a
full backup every night. We keep the weekend fulls at a different
retention than the weekdays, and backing up this much data makes a
recovery very simple. I have reviewed the incremental notes backup,
and
it appears to only get the transaction logs. We have not tested a
restore from this type of backup, so I don't know how well it works. I
think we might just be lucky so far that we've never needed to roll a
data file forward from logs. Usually we're restoring the entire .nsf
file and letting users attach to the current and previous one to manage
the differences.
Along with the full .nsf backups for mail, we also get the transaction
logs. I don't think I've ever needed to use them.

Hi Boris,
We did transaction log bkups until recently, as we were never able to
get
our "point in time" recoveries to work. I suspect that it's
because of the
length of time it takes to do the database backup (couple of
days for just
over 1TB over the LAN). We also multi-streamed the transaction and
database backups to ensure that the transaction log file(s) would be
reinitialized.
I'm still VERY interested in seeing how other sites are doing their
Notes
backups/restores.

Hi Steve,
I have to get back to this topic. Do you do transaction log
backups using
NBU add-on database agent for Lotus Notes? How it works for you?
We are
still doing file level backups with regular NBU client for
Windows. I was
asked to evaluate transactional log backups as well, we have a few
mail
servers with 0.5TB data on each. We backup them over LAN, I am
thinking to
convert them into SAN media backup servers. Any useful
information on how
you do the backup for Domino environment would be really helpful.
I saw Jerry also responded on this topic. Jerry, could you
please be more
detail how you do VSS or I can see you do the array based solution
with
local copy cloning, correct?
Does anybody do transactional log backups for Domino Notes?
Any pros and
cons?
Curtis? maybe you can get back on this one.
Thank you,
Boris

Hi,
We've been "wrestling" with this for quite some time, and
very curious to
see how other sites are managing their Lotus Notes backups.
We're running
NBU6.0 MP4 (servers and clients). The database is just over
1TB and we do
transaction log backups.
Thanks,
/Steve
