The Backup Process

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.
