    Know Your Citys 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. Lets save the trees entrusted to us by

    past generations, and plant new ones for the future.

    We hope youll use this contest as a fun way to get to

    know your citys trees!

    Whats Your Backup Plan? TNBs Data Safety Guide.

    Will your data always be there for you? Lets

    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 clients 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 storagein which

    your data is stored in a secure server on the

    Internetprotect 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

    Jenns 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 shes 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 Universitys 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.
