Data matching algorithms<\/h2>\n

CyberSecure Standard\/Advanced includes delta-matching technology that enables in-file incremental transfer, which greatly reduces the bandwidth needed to send files, plus means that previous versions are also stored efficiently being just the “delta” patch file.<\/p>\n

However to achieve this, the following conditions must be met:<\/p>\n

    \n
  1. The previous + new file name must match exactly<\/li>\n
  2. The previous + new files must have different timestamps<\/li>\n
  3. The new files written must be in some type of pristine, uncompressed, unencrypted and consistent state.\n
      \n
    1. eg. A ZIP file structure is different each time it’s written – this interferes with the delta matching algorithms and means the whole file is uploaded each time. If you are trying to backup a backup file from an application that generates a ZIP file, the backup will not be efficient as the whole file will be uploaded each backup.<\/li>\n
    2. A better strategy is to point the backup at the original data (eg using our SQL database module for Advanced edition), or by first uncompressing the ZIP file to a temporary location.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
