Our next obstacle is the infrastructure for the base on the moon. The Moon will be used as stopping point on the way to Mars, in addition to serving as the human race’s new home until the colony on Mars is finished.
Due to the way the base was constructed, we have serious power, cooling, and space limitations. You must scale the design down to fit into half of a datacenter rack, or 21U. In addition, we also only have IPV6 network infrastructure on the moon. You must use the same vendors of the design you will be working with, but you can use different product lines. You must tell us what the configuration maximums for the new design are (for example, maximum hosts, VMs, storage capacity), and what your failure tolerance is.

Covey says most people look for quick fixes. They see a big success and want to know how he did it, believing (and hoping) they can do the same following a quick bullet list.
But real change, the author says, comes not from the outside in, but from the inside out. And the most fundamental way of changing yourself is through a paradigm shift.
That paradigm shift is a new way of looking at the world. The 7 Habits of Highly Effective People presents an approach to effectiveness based on character and principles.
The first three habits indeed deal with yourself because it all starts with you. The first three habits move you from dependence from the world to the independence of making your own world.
Habits 4, 5 and 6 are about people and relationships. The will move you from independence to interdependence. Such, cooperating to achieve more than you could have by yourself.
The last habit, habit number 7, focuses on continuous growth and improvement.

Create A Backup Script Version 1 R3
1 Prerequisites
Before you begin creating a script for performing a backup on remote systems, there are a few
tasks you should accomplish.
1. Have a, thoroughly planned backup strategy
2. Have, installed and configured the Retrospect Client on all remote systems
3. Discovered and added clients to Client Database
4. Double check available HDD/NAS/SAN space allocation
5. Double check client/server connectivity

4. Retrospect Guide Nathan Peek 2010
Create A Backup Script Version 1 R3
2 Prep
Something I like to do before creating a script is define volumes. For me, I’ve found during the
script creation process, though convenient, defining your volumes can be a hassle. If you have a
planned strategy and you know exactly what it is you want to backup it is simple to jump in and
define your volumes beforehand. Though unnecessary, Retrospect will allow you to define
volumes later in the script creation process; you may find defining volumes may even run faster
when accomplished as a preparatory task.
DEFINING
• Open Retrospect drop down the Configure menu.
• Select Volumes
• Select the “Plus‐Down” for Backup Clients
• Highlight the directory where you want to drill down into and click the “Subvolume…”
button
4
5. Retrospect Guide Nathan Peek 2010
Create A Backup Script Version 1 R3
• In the “Subvolume Selection” window you can continue to drill down by double clicking
each subvolume (directory parent folder)
• Here I will select /etc and /bin by holding Ctrl and selecting both volumes
• Select Define
• The subvolumes should then be populated underneath the parent directory of the client

• Select Manage Scripts
• Select New…
• Here you will be faced with numerous options. The purpose of this guide is to
create a Backup Script
• Highlight Backup and select OK
• Give the new script a name.
o If backing up a single client my standard is to name the script as
Volume(s)_ClientName
• Select OK then Next >
• You’ll be asked what you want to backup. There are 4 options to choose from. I will
select “Let me choose (Advanced). I do this for flexibility purposes. I have specific
folder/files/volumes I backup in my environment and never allow Restrospect to
arbitrarily select my data for me. Now select Next >

• This is where your prep will glean the most benefit. Plus‐down your client and Ctrl
select the volumes you want to backup, select Next >
o Here you can also Add additional clients or add other volumes that are network
attached such as a share or perhaps a NAS volume, for our guide I are adding
volumes directly from remote client(s) directories
• When asked “What types of files do you want to backup?” select the appropriate box
based on the data inside the volumes you are backing up. In our example the /bin and
/etc directory don’t necessarily contain any images, music, or movies, etc. therefore I
can de‐select each box aside from “All other files”. Select Next >
o In our example it doesn’t matter whether or not I de‐select any of these boxes.
Retrospect will not continue searching the directories for these file types if they
do not exist.

• Navigate to the location you will put all of your backup files. For consistency, I typically
name the folders the same name of the backup script. Select Next >
• You can create a backup schedule now or you can do so later. I’ll do so now. Select the
“Create a schedule for this backup” radial button and select Next >
o Select the day and time of day you want your backup to run. Select Next >

• When asked “How many Backup Sets would you like to use?” you must consider a few
questions before selecting whether you want one or more sets of your data
o How much data do you have?
o How much space do you have for your data?
o How much data do you expect to have in the future
o Do you have the ability to expand space?
o How reliable is your software and hardware?
o How many copies of your data do you already have?
o Are you configured with RAID on your backup system?
o Do you plan to archive and store data?
• In my environment I have little data compared to a full‐on enterprise. I have a RAID 5
configuration that spans 6 500GB drives with a total of about 3.5 TB to play with. What I
backup, though crucial, is also backed up on a shared space and sometimes locally. I
archive my data monthly and clean any duplication that may have occurred. Also, the
potential for our data to grow significantly exists and therefore I choose the “One
Backup Set” option. You could choose either; whatever works best for your situation.

• Name your backup set(s). Click Next >
• When asked, “Would you like to compress your data?” is really up to:
o How much time you have
o How patient you are
o How much space you have
o I don’t compress any of our data. I have plenty of space in my environment and
my hardware is scalable. If you have a limited amount of space you could
compress your data to save space. Remember, this will take a significant
amount of time to do so and in reverse you’ll have to decompress when
restoring data.
• Retrospect has two main methods of encryption. First is a hardline encryption that will
encrypt the data as it is backed up on the wire. The second is encryption of the data
itself. I ALWAYS, as a standard, AES‐256 encryption. It is the most secure and, based on
DISA STIG and other USAF recommendations, is generally accepted as the only way to
go.
o When placing a password for this encryption it is recommended to put a 14
character – alpha numeric – numbers – caps – loIr case – special characters
o In the “Would you like Retrospect to remember this password?” drop down I
leave the “Remember password for scripted access” option (default) selected. I
found when utilizing a backup schedule for a nightly or Iekend backup allowing
Retrospect to fill in the password on its own keeps from permissions issues on
backup files later on.

• When asked “What do you want to do when you backup drive becomes full?” window,
this can be complicated
o First, as a backup administrator you should never allow your space to become
so full the software has to recycle or remove data as a solution
o HoIver, if you plan is to leave the backups run and never manually clean your
data you can select “Keep only the last XX backups”
o You can also utilize Retrospect’s policy and which will keep the source data for
every day in the last Iek, each Iek in the last month, and so on
o In my environment I must keep EVERYTHING. Because Retrospect only backs up
what has changed since the previous backup my data does not grow
exponentially unlike a Proactive Backup (see Proactive Backup Genius Guide).
Also, I archive my data each month, monitor backup trends, analyze disk usage,
and have scalable hardware capable of supporting multiple terabytes of data.
o I select “Ask for a new disk” as part of my backup strategy. Click Next >

• To complete the script you have the option to backup all the scripted data immediately.
I would base whether or not you “Backup Now” on:
o Time of day
o Network usage
o Amount of data
• Generally, for small amounts of specific data I would go ahead and backup immediately
to get the ball rolling. If you choose to backup according to schedule and NOT backup
immediately then check back after the backup has ran to troubleshoot any errors if any
occur.

• When you select Finish, if you decided to Backup immediately the Activity Monitor will
initiate in the executing tab.
o When the script completes you can select the History tab in the Activity Monitor
to see if you script completed successfully.

4 NOTES
In my experience the retrospect client commonly idles on linux machines. If this happens
and you are not able to access your linux machine from your client database simply PuTTy to
your box and run the retroclient script in /usr/local/dantz/client. Or you may need to go to
the machine and local open a terminal and run the script as root
For more detailed information about your script you can select the Reports plus down on
the left hand menu and select the Operations Log.
