Back it up or pack it up! Did you know that 60% of all small businesses that lose their data are out of business within 6 months? Don’t be one of them! Your New Year’s Resolution for your business should be to setup a backup solution, or evaluate the one you have. Come to TechComm this month to learn more about proper backup solutions.

Backup Solutions
Intro
Get something in place ASAP
Don't get paralyzed because you can't do everything
Almost anything you do will be better than doing nothing
Considerations / Planning
Identify the problem
Recovery time
Backup schedule
Retention time
2 Distinct Problems
Entire computer will not boot or was destroyed
A “few” files were damaged or deleted
How Quick do you need recovery?
When disaster hits, can you wait a few Minutes? Hours? Days?
Faster recovery == More money
Backup Schedule
How much can you afford to lose?
Absolutely nothing?
A minute?
An hour?
A business day?
A whole week of work?
Time of day
Not necessarily in the middle of the night
More frequent == More complex
Keep Backups for how long?
Backup retention
How long to keep the backups
How many copies
How long will it take you to discover the problem?
Weekends + holidays = delays
Embarrassed employees = delays
Consider the Material
Different solutions for different stuff
Data files
Large files: photos, videos, audio
Purchased programs
Operating system
Some material might not be on your computer
Receipts
Installation media
Certificates of authenticity / Product Key Codes / Activation Codes

Backups are a Process
Backup software is just the first step
1) Plan your backups
2) Execute the plan
3) Test now. Don't wait for a disaster!
Backup Types
Full System Backup (OS, Applications & Data)
Full Data Backup
Incremental vs Differential
Differential backup offers a full system backup at regular intervals, so naturally it
takes longer and requires more capacity.
Example: (Weekly) Do a full backup every Sunday. Then on Monday, only files that have
changed since the full backup on Sunday. On Tuesday, only files that have changed since the
full backup on Sunday (Essentially, the Tuesday differential replaces the Monday differential)
Incremental backup only backs up files that have changed since the last backup (full
or incremental), so it's quicker but has a longer recovery time since it has to restore
data from multiple incrementals
Example: (Weekly) Do a full backup on Sunday and incrementals during the week. On Monday
only data that has changed since Sunday and then on Tuesday, only data that has changed
since Monday, etc. So if something happens on Saturday, you would need to use 6 backups to
restore data.
Versioning
allows you to keep different versions of the same file – You have edited the files
several times and don't want the next backup to over write them.
Cloning (or Imaging)
a hard drive creates an exact replica of a hard drive
Minimizing Risk - Common Causes & how to minimize risk for each:
Human Error
Proper File Security
Software (Corruption)
Reputable, up-to-date OS/drivers & applications
Hardware Failure
Quality Hardware
Temperature - kept in room temp or cooler environment
Redundancy
Less Mechanical Parts
Other Considerations…
Turn off synchronized backup, if possible
Disconnect external backup when not in use
A backup plan is typically more cost effective than a recovery attempt

Backup Solutions:
1) Secondary Drive in your machine (mirroring)
2) Tape Drive (old magnetic media technology - phased out)
Consider the technology – if the unit is destroyed, could you get a replacement to read the
backup medium?
1) CD/DVD (smaller capacities – maybe ok for archiving)
2) USB Flash Drive (smaller capacities)
3) External USB Hard Drive (Constant Connect)
4) External USB Hard Drive (Rotational Off-site or FireSafe)
5) Another PC
6) Cloud Storage
7) Disaster Recovery Center
Solution
Pros
Cons
Secondary Drive (mirroring)
Quick recovery
Only protects against hard drive failure
Tape Drive*
Cheap media
Old technology (phased out)
*If machine is destroyed can you find a
replacement to read the media?
CD/DVD*
Cheap media
OK for Archiving?
Limited Capacity
USB Flash
Reliability
Limited Capacities/Cost
*Smaller capacities are cheap, but larger
capacities are more expensive

(unless SSDs are used)
Onsite - subject to similar issues
Slow backup & recovery
$$$
Speed of Recovery (from fastest to slowest):
1) Connected internally in machine (SATA, etc)
2) Connected externally to machine (USB)
3) Connected to Internal Network (another PC on the network – 100 Mbps)
4) Connected to Internet (only as fast as your download speed ~ 1.5 - 50 Mbps)
- Likewise, backing up relies on your Upload Speed (~512 kbps - 10Mpbs)

Solution
Offsite Backup:
Rotational Offsite
Cloud
Disaster Recovery Center
Any solution, provided it was not in the same place & could
have also been stolen/lost
Any Solution, but the key here is time taken to discover the
deletion
Any Solution, provided it was not also connected to the
machine at the time of infection (Ex: Cryptolocker)
Seriously, though…Backup your files!
Tech Tip: Belarc Advisor
Belarc Advisor is a piece of software that can look up your various software
installation keys, it is a free download for individuals.
