Subject: [Networker] Solstice help needed
Hi,
I got your mail id from the Networker mailing list at
https://listserv.temple.edu. Sorry to write to you directly, but I am
very new to the world of Networker and there is no one to help / guide
me. So I see your advise. This is what the scenario is:
Server OS: Solaris 8
Networker: Solstice Backup server 6.1
Tape: HP Sure Storage 4/40 with autoloader
Now, my doubts are:
We user the Ultrium tapes with 200 GB capacity. But when I do a media
check, I get the following:
# mminfo -m
volume written (%) expires
read mounts capacity
BD5445L1 109 GB full 08/16/06 0 KB
57 100 GB
Why does the capacity show only as 100 GB. How can I change it to
recognize as 200 GB. The data tapes are 200 GB Part #: C7971A and the
cleaning tapes are: Part #: C7979A
>>> This is the native documented capacity of the drive. Compressed
capacity can vary depending on what you backup to these tapes.
I have only 2 groups which I backup (NT & UNIX) and I want to have an
offside backup, I can create a group called backup and add both my
groups to the pool and copy the data every weekend. But if this building
catches fire, how will I recover from the tapes that are sitting in a
different state.
>>> Your offsite backup tapes will contain the bootstrap. Bootstrap is
a collective saveset of NetWorker's media database and resource files.
In the event the production site goes down, you setup a similar
server/tape configuration in the new site and use the off-site tape to
rebuild the NetWorker databases. Refer to the "Disaster Recovery Guide"
for further details
How can I configure that some other machine in a different state can
recover from the tapes. Even if so, do I need another HP Sure Storage
4/40 to read the tapes ??? If not how can I have a DR plan.
>>> You need a compatible tape drive and the backup server with the same
OS, Host name and IP address. A compatible tape drive means a drive
that can "read" your 4/40. For ex: You can have off-site DLT7000 tapes
but can use a SDLT320 drive to read the DLT7000 tapes.
The HP Sure Storage 4/40 has 40 slots. I am now aware what is the
mailslot and what is the cleaning tape. We use barcode reader and I have
stickers from a company called Tri Optic for the data tapes but I do not
have any labels for the cleaning tape. Can you advise me what is the
cleaning tape and the mail slot used for.
>>> A mail slot is used for loading/unloading tapes without opening the
door of the library. Your vendor should be able to give you a cleaning
tape bar code as well. Or you can use the bar code as your data tapes
but that would be confusing. So long as you have configured "Auto clean
: Enabled" for your library and have the cleaning tape inserted in the
correct slot, the barcode should not cause a problem.
How can I order more labels for the cleaning tape and once I receive
them, how do I tell Solistice to recognize it (Do I do an inventory)
Also which slot should the cleaning tape go to.
>>> If you have "Auto clean" enabled for your library, the cleaning tape
usually goes to the last slot available on the library. If you wish to
have more than one cleaning tapes, you can modify the "Cleaning Slots"
attribute of your library. On inserting a cleaning tape, you can do an
inventory for Solstice to recognise it. (But I don't think the inventory
will load the tape to read it, unlike data tapes).
What is the normal life of these tapes. I assume they have not been
changed in last 4 years. How can I tell they are expired or if they need
replacement. I do not want to be in a situation that the tape from where
I want to recover, is corrupt or damaged.
>>> I think, the best person to answer this question will be your tape
vendor.
Solstice is running on UNIX. I am not unix admin and I think I should
move it to a Proliant server running Windows 2003 server configured with
RAID 5 so that even if there is HDD failure, I can swap the HDD and the
raid will build by itself. I have licenses for 10 clients. What would be
the best way to do this.
>>> Solstice is the NetWorker version bundled for Solaris. I am not too
sure if you can convert this license to run on Windows boxes. Check
with your vendor.
if I do have a offside group, and run the backup of the tapes to the
group every week end, I guess I will have to change/remove them on
Monday and send them. Isn't it.
>>> Yes, unless you have setup an remote storage node and are
cloning/backing up to it.
What is cloning. Is that similar to doing an offside backup group ?
>>> Cloning is the process of copying your backup data from the backup
tape to another tape. At the end of a successful cloning, you will have
two copies of the same data in two different tapes - one to keep onsite
and the other offsite.
As a newbie what can I check to make sure the backup's are fine and
incase of a recovery scenario, I am not found unprepared and lose my
job. I do /usr/sbin/nsr/mminfo -t 'yesterday' to check the files backed
up over night. What else do I need to check.
>>> Best way is to check the group status individually every morning.
You can also setup "Savegroup completion" notifications to have emails
sent to you automatically.
Can you give me a DR plan that I can try and implement. I am
thinking of having a test machine (each of UNIX & NT) and back them and
then thrash them and do a recover. Any guidance on doing this.
>>> Refer to the "NetWorker Disaster Recovery Guide". This explains
different scenarios of disasters and how to perform recover in each
situation.
What happens in the scenario that the backup server which runs the
Solstice software has a HDD crash. How can I recover files then ??
>>> Refer to the "Disaster Recovery Guide". You can also refer to the
"scanner" and "mmrecov" man pages.
Sorry to ask so many questions, but I do not know who can help me. I
am trying to get some help on Solstice from a couple of months and I
would appreciate if you could guide me. Thanks a lot in advance.

karnash
