NovaBackup comes with a free, one-year, 2GB DigiStor account that is customized to mesh with NovaBackup, though you need to provide credit card information to use it if you don’t want to keep it, however, the account will be canceled, not automatically renewed. It also allows you to apply the same settings to your local backups so that you’re always sure you have everything backed up to each location. Not that the backup clients for other online services are bad, but using NovaBackup’s advanced options and GUI simply make it that much easier. If you have an Amazon S3 or NovaStor’s Digistor, you can simply add the service as a device, enter your user info, and then select it as the destination for any of your backups. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software.įor more detailed and personalized help please use our forums.I enjoyed my hands-on trials with NovaBackup 10 tremendously–especially the seamless integration of online backup storage. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. UDP is often used with time-sensitiveĪpplications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data. The message to process any errors and verify correct delivery. Like TCP, UDP is used in combination with IP (the Internet Protocol)Īnd facilitates the transmission of datagrams from one computer to applications on another computer,īut unlike TCP, UDP is connectionless and does not guarantee reliable communication it's up to the application that received Guaranteed communication/delivery is the key difference between TCP and UDP. TCP guarantees delivery of dataĪnd that packets will be delivered in the same order in which they were sent. To establish a connection and exchange streams of data. TCP ports use the Transmission Control Protocol, the most commonly used protocol Used port numbers for well-known internet services. IANA is responsible for internet protocol resources, including the registration of commonly Ports are unsigned 16-bit integers (0-65535) that identifyĪ specific process, or network service. Port numbers in computer networking represent communication endpoints. Retrospect backup and restore service, modified: Port is IANA registered for: Dantz Retrospect backup and restore service References: ĮMC Dantz Retrospect 7 backup client 7.0.107, and other versions before 7.0.109, and 6.5 before 6.5.138 allows remote attackers to cause a denial of service (client termination and loss of backup service) via a malformed packet to TCP port 497, which triggers an assert error. References: īuffer overflow in EMC Retrospect Client 5.1 through 7.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted packet to port 497. Retroclient.exe in EMC Dantz Retrospect Backup Client 7.5.116 allows remote attackers to cause a denial of service (daemon crash) via malformed packets to TCP port 497, which trigger a NULL pointer dereference and memory corruption.
