Know Your City’s Trees! December Contest
Where in South Boston are these trees? The
first reader to guess their location will receive a free gift.
Last month, Southie Trees arranged a tree planting in
South Boston, to implement a grant from Grow Boston
Greener to plant four flowering cherry trees. Many South
Boston residents and businesses supported the event.
Tech Networks of Boston supports the preservation of
mature urban trees, which make neighborhoods more
pleasant, filter our air and water, and moderate
temperatures. Let’s save the trees entrusted to us by
past generations, and plant new ones for the future.
We hope you’ll use this contest as a fun way to get to
know your city’s trees!
What’s Your Backup Plan? TNB’s Data Safety Guide.
Will your data always be there for you? Let’s
find out. When Tech Networks of Boston
creates your Data Safety Guide, our technicians
will work with you in a structured planning
session to ensure your data is always available
when you need it. Your data safety system will:
! Protect against data corruption or loss
from hardware failure, malware, natural
disaster, human error, theft or sabotage.
! Meet current and future capacity,
retention and recovery needs.
! Back up data reliably and efficiently.
! Cause minimal inconvenience to regular
business operations.
! Restore lost data and bring failed
systems back to normal operation
within the client’s time frame.
! Meet your budget and use funds wisely.
In most cases, TNB recommends a hybrid
backup structure that gives you the advantages
of three different technologies: tape or disk-to-
disk backup, on-site network storage, and
secure cloud storage.
Offsite solutions like cloud storage—in which
your data is stored in a secure server on the
Internet—protect you against disaster or foul
play at your physical location, with the
disadvantage of potentially slow transfer speeds
should you need the data recovered quickly.
Onsite solutions including disk-to-disk backup
are much faster to store and recover data, but
create a single point of failure. This is why the
best backup solutions use multiple technologies
and approaches, selected to complement each
other in serving your needs.
Inside, read more about some of the factors we
consider in creating your Data Safety Guide.

Type of Backup Advantages Disadvantages
Full / Image Backup: All data Is backed up, either by copying all files to a backup location, or by making a copy (“image”) of the hard disk.
Full copy of data in one place makes it easier to accesss a particular needed file.
Slow because it includes the largest amount of data. By storing multiple copies of the same files, multiple full backups can be inefficient.
Differential Backup: All files created or changed since the last full or image backup.
Faster to restore than incremental backups: only two backup sets are needed (the latest full and differential).
Longer and larger backups than incrementals. The size and backup time increases with each backup.
Incremental Backup: All files created or changed since a full or incremental backup.
Fastest, most efficient use of media by backing up the smallest amount of data.
Complex restores require multiple incremental data sets. Also, one set could fail.

Meet a Boston Techie
!
Hailing from Northeastern University as an
environmental science major, Jennifer Brundage has
been involved in TNB events ranging from sales
conferences to alternative energy rallies.
In addition to her work editing Boston Charity Events
and Boston Techie newsletters, TNB devotes half of
Jenn’s time to Southie Trees. As head coordinator,
she has been in charge of organizing tree plantings,
grant proposals and campaigning to save heritage trees
in the Old Colony housing development.
When she’s not working, Jenn volunteers for three
different bicycle advocacy groups: the Boston Cyclists
Union, Commonwheels Bicycle Coop, and Bikes Not
Bombs. She also works as a sound tech at
afterHOURS, Northeastern University’s music venue.
These tables show some factors your TechAdvisor will consider in your Data Safety Guide.
We will fill Table 1 with an inventory of your data. Table 2 explains the different backup
types, and Table 3 illustrates the expected data recovery times for different technologies.
TNB will consider all these and more to ensure your information is safe and recoverable.
