Connection

Use cases

  1. Your company's network has tight security, that incorporates firewalls or deep packet inspection software which interferes only with encrypted traffic. In this case, Acronis Connection Verification Tool will report the connection to be successful, yet the backup will fail. Once an unknown certificate is present in the chain, Acronis Storage rejects the connection.
  2. On MacOS, there is no Acronis Connection Verification Tool yet. OpenSSL can be used as a replacement for it.
