The most important new features are the faster processor, a 1.5-GHz Broadcom CPU and GPU, more and faster RAM, the addition of USB 3 ports, dual micro HDMI ports (instead of a single HDMI connection) and support for 4K output. If all you’re doing with your Pi is running a security camera or playing old arcade games, you might be able to stick with what you have, but you’ll definitely want a Pi 4 for future projects. The newer platform has a number of distinctive advantages, including speeds that are two to four times faster, support for USB 3 and true Gigabit Ethernet and dual video output with resolutions up to 4K. However, if you’re looking for an all-around, general purpose Raspberry Pi, there’s no doubt that it’s the Raspberry Pi 4, which goes by the official model name of Raspberry Pi 4 B (there’s no 4 A, so the B is superfluous).īut let’s say you already own a Raspberry Pi 3 or an earlier model and are wondering if you should also get a Raspberry Pi 4. But choosing which Raspberry Pi to buy is an open question because there are reasons you might want to get a different model, such as the $5 Raspberry Pi Zero. Every single-user system should have this software for redundant storage of critical data.Raspberry Pi 4 Model B (Image credit: Tom's Hardware)Įlsewhere, we've outlined extensively why every tech geek should own a Raspberry Pi.
FreeFileSync gets along perfectly with external mass storage devices as the target disk and can also quickly synchronize larger databases. The add-on program RealTimeSync automatically carries out synchronization jobs you do not need to worry about anything after a one-off setup. ConclusionsįreeFileSync is a powerful tool for data synchronization on small networks it does not, however, perform real backups with incremental or differential runs. This delay is a very good idea, especially on busy file servers, because continuous synchronization of data with external mass storage devices would significantly affect the speed at which your server provides its services. If changes occur, it automatically synchronizes the files concerned and briefly displays a progress bar on the desktop during this process.ĭepending on the chosen interval – Idle time (in seconds) – the software synchronizes the directories with a delay. The program is then minimized into the system tray of your desktop environment and monitors the designated folder for changes from now on.
Figure 7: RealTimeSync permanently synchronizes the data of monitored folders with the synchronization target.
