The following image displays this relationship visually:

The following assumptions are made in the above example:

• Syncrify Server is running inside your network
• The private IP Address of this machine is 192.168.1.20
• The public IP Address of this machine is 205.204.203.1
• You have also configured your DNS server to map backup.yourDomain.com to point to the public IP Address
• Syncrify is listening on TCP/IP port 80
• Your firewall has been configured to allow inbound traffic on port 80 to 192.168.1.20

Client A connects from the Internet using the following URL:

http://backup.yourDomain.com

OR

http://205.204.203.1

Client B connects from withing your network and can use the following URL: http://192.168.1.20

When a backup job becomes active due to a manual or a scheduled process, the computer performs the following sequence of operations:

1. Scan the hard disks to identify the files that need to be backed up.
2. Common file technology is applied for duplicate file elimination
3. Delta block differential technology is applied to determine the part of the file that has changed.
4. Smart compression algorithms are applied to further decrease the size of data transferred. If compression does not change the file size significantly, this step is omitted to save CPU cycles. This is important when transferring files that are already compressed or are in a format that does not benefit from compression, such as, MP3 or JPG.
5. When using HTTPS, data transfers to the server are encrypted by industry standard SSL encryption.
