For experienced users, CmosPwd offers a way to read or modify passwords. Because these passwords are stored in EEPROM modules on many computers, especially notebooks, unrestricted access is not possible. SystemRescueCd also comes with some forensic programs, including chkrootkit, which scans the computer for hidden malware that opens a back door for attackers, and CmosPwd, which reveals BIOS passwords. Like Bonnie++, you control the stress level through a variety of parameters (see the list with stress -help) htop then lets you see how much stress the system is under. On the other hand, the Stress benchmark tool creates high load on various hardware components (e.g., CPU, memory, bus). The most popular, Bonnie++ and Stress, are launched in a terminal window and thus don't appear in the Xfce menus.īy measuring the read and write throughput of mass storage devices, Bonnie++ can provide information on possible hardware defects in the event of poor system performance. Extra Equipmentįor performance comparisons between individual hardware components or complete computer systems, SystemRescueCd comes with a number of prominent benchmark programs. Although its name suggests otherwise, Photorec is not limited to restoring digital images: It also knows many other file formats and reconstructs them. The duo restores accidentally deleted data or data that is no longer accessible because of a hardware defect. Photorec, which is also called in the terminal, teams up with Testdisk for data reconstruction. Its numerous options are revealed by the tob -help command. Search for Rsnapshot in the SystemRescueCd menus in vain – the software is called directly from the command prompt.ĭespite its name, the tob (tape-oriented backup) shell script not only saves data on tape, but also on conventional filesystems. However, newer backups inevitably depend on the older ones – if they are missing, the reconstruction fails. With multiple snapshots on a single target medium, Rsnapshot only saves copies of unchanged files once it then uses hardlinks to these files in subsequent snapshots, saving storage space. It is also suitable for the use of an external USB hard disk as a backup medium. The Rsnapshot command-line program, which is also based on Rsync, creates snapshots of entire partitions – much like Partition Image. It is based on Rsync, the well-known sync software. Figure 6: The small Grsync tool synchronizes your data with just a few mouse clicks.
