Netcom Enterprises RSync Off Site Backup Solution
r1.09a
Rsync is a Windows based
software application used to synchronize files and directories from one location
to another while minimizing data transfer between each location.
The data transfer is
minimized using an algorithm that will transmit, roughly speaking, only the
parts of the backup selection that have changed, right down to a bit level
transfer. (This technology is also known as in-file delta incremental transfer.)
Along with this minimized data transfer Rsync also compresses all data packets
sent, further reducing transfer overheads. To do this bit level data transfer
Rsync uses a checksum method. This method creates a short alphanumeric string
based on the data it represents. Rsync firstly checks whether any data has
changed by looking at file size and modification date. If no data has changed
then Rsync will not transfer any unnecessary data, saving you time and
bandwidth. If, however, the files do not match, then Rsync uses a checksum
method called a ‘rolling checksum’ on the changed files to see where it has been
altered or appended. It will then transfer only the altered or appended data
within the file. With these two methods Rsync can cater for inserted or added
data, removed data as well as shifted data, with a minimum transfer
overhead.
In real terms, what this
means is more efficient use of your bandwidth and data allowances. As Rsync will
only transfer data that has changed and knows when file alterations or movements
have occurred, your Internet based backups will take a lot less time when
compared other methods.
The
key benefits of Rsync:
Improves offsite backup
speed through bandwidth optimization.
Reduced network data
transfer by only transferring new data.
Open standard secure
protocol – RSync over SSH for maximum security, compatibility and
flexibility.
Rsync via a secure shell (SSH, port 22) means that all traffic
over the internet is encrypted.
Scheduled automatic
jobs.
