According to the survey, computer users have always been troubled by problems such as computer crashes, hard drive crashes, and excessive memory chip loss, and the best solution is system restore. The purpose of "System Restore" is to return the system to a working state without reinstalling the operating system or destroying data files. Therefore, based on the latest information and data released by the Techradar website, IDC Review Network introduces ten commonly used Linux system restoration tools to everyone.
1 Photorec
Photorec is a free, cross-platform command line tool that can help users recover accidentally deleted photos. At the same time, Photorec can recover almost any other file format from the user's removable media or hard drive.
It is reported that the areas that Photorec can cover include hard drives, optical discs, USB drives, memory cards and even portable music players such as iPods. It can read data blocks in FAT, NTFS, EXT2/3 and HFS+ partitions, and can help users find Recover files in more than 300 popular formats, including ZIP, HTML, PDF, and JPG.
2 e2fscktools
Modern operating systems must perform many read and write operations every day. As time goes by, users are likely to find that the file system is inconsistent one day. This requires tools similar to e2fscktools to check and modify EXT2, EXT3 and EXT4 files. system. At the same time, users can also use e2fscktools to mark disk bad areas, so they are not suitable for storing data.
For other file systems, users can use xfs_repair, jfs_fsck, and fsck.resiserfs to detect and repair them.
3ntfsresize
Like the e2fsck tool, the ntfsresize tool is included in most mainstream Linux desktop distributions, and it can help users resize 32-bit and 64-bit Windows partitions. This tool can check for NTFS partition errors when the user wants to expand or shrink the file system.
4FSArchiver
For a damaged disk, the only effective solution is a backup. Although there are many backup tools in the current market, none of them are as good as FSArchiver.
Through FSArchiver, users can save the contents of the file system into a compressed archive, which can help users save space. The backup data also supports read and write formats.
5 chntpw
There is no doubt that password protection is a good way to ensure account security, but users often forget the account passwords they set. Currently, most web services have a backup plan that can help users retrieve their passwords, but Windows does not have this feature.
When users forget their Windows password, the chntpw tool can come in handy, it can help users reset their Windows installation password.
6.Sfdisk
If the user installs multiple systems on the computer, it is easy to cause confusion in the partition table. Tools such as Gparted mean that creating and resizing partitions is no longer a chore, but when faced with a misaligned partition table , Gparted does not work.
Here, the author recommends the Sfdisk tool to everyone. It is a small command line tool that is bundled with various Linux distributions and can be used to back up, edit, and restore partition tables. It is reported that users can use sfdisk -d /dev/sda 》 sda_table.txt to back up the partition table, and use sfdisk /dev/sda 》 sda_table.txt to restore the partition table. If RAID is installed, you can also use sfdisk -d /dev/sda | sfdisk /dev/sdb to back up the partition table.
7ddrescue
Users have always looked for tools that can help them check and correct damaged partitions, but users are often at a loss when ancient disk or optical drives have read errors. At this time, users can try to use the DDRESCUE tool to back up the damaged disk, and then try to repair the backup.
8 chkrootkit
Computer viruses have always been a program that users worry about. Chkrootkit can help users check the status of installed programs and scan for intruders through many well-known rootkits.
9 GAG
When users install multiple operating systems or clone a boot partition, MBRs can easily be damaged. At this time, users can switch to the GAG boot manager.
It is understood that installing GAG in the primary partition or logical partition of the disk can boot 9 different operating systems. It can bring users all the functions expected by the boot manager, including timers and configurations to enter the default operating system. Password protection of menus.
10 Rsync
Users can use the Rsync tool to back up data over the network, and it is a very practical application.
