4MRescueKit provides its users with software for antivirus protection, data backup, disk partitioning, and data recovery. It is distributed in the form of a multiboot CD, which includes four (extremely small) operating systems. Each of the systems tries to follow the UNIX philosophy (Small is beautiful. Make each program do one thing well).
1) Antivirus Live CD is a 4MLinux fork including the ClamAV scanner. Both Ethernet (including
Wi-Fi) and dial-up (including fast USB modems) Internet connections are
supported to enable automatic updates of the virus signature database.
All partitions are mounted automatically during boot so that they can be
scanned by ClamAV.
NOTE:
Detailed description of Antivirus Live CD can be found here.
2) BakAndImgCD is a very small (about 20 MB in size) 4MLinux fork, which has been designed to
perform the following two tasks: data backup (via 4MLinux Backup Scripts) and disk
imaging (using Partimage, Partclone and GNU ddrescue). The output files
(archives and images) can be optionally compressed and sent to a remote
FTP/SFTP sever.
NOTE:
Detailed description of BakAndImgCD is available in this post.
3) 4MParted includes GNOME Partition Editor (aka GParted), which in turn is a GTK+ front-end to GNU Parted.
The supported filesystems are: btrfs, ext2, ext3, ext4, f2fs, fat16,
fat32, hfs, hfs+, jfs, linux-swap, lvm2 pv, nilfs2, ntfs, reiser4,
reiserfs, and xfs.
NOTE:
If GParted cannot read/modify a newly created partition, just close this application. Then 4MLinux will try to force the Linux kernel to re-read partition table, and next it will restart GParted for you.
4) 4MRecover includes TestDisk and PhotoRec,
which are powerful recovery utilities. PhotoRec (the tool to recover
lost files) is started automatically. Just close PhotoRec, and Midnight
Commander will be opened so that you can manage your files. You can also
execute "testdisk" (in Midnight Commander's shell prompt) if you are
going to try to recover lost partitions.
NOTES:
Despite its name, PhotoRec is able to recover many file formats (not only images).
All operating systems described in this post can be safely closed by pressing the power-off button (acpi daemon will start a script to cleanly shutdown your computer).
