Redo Rescue, formerly Redo Backup and Recovery, is a free backup and disaster recovery software. It runs from a live CD, a bootable Linux CD image, features a GUI that is a front end to the Partclone command line utility, and is capable of bare-metal backup and recovery of disk partitions. It can use external hard drives and network shares.
Foremost is a forensic data recovery program for Linux that recovers files using their headers, footers, and data structures through a process known as file carving. [3] Although written for law enforcement use, the program and its source code are freely available and can be used as a general data recovery tool.
Quick crash recovery on-mount; Read-ahead for meta data files as well as data files; Block sizes smaller than page size (e.g. 1KB or 2KB) Online resizing (since Linux-3.x and nilfs-utils 2.1) Related utilities (by contribution of Jiro SEKIBA) grub2; util-linux (blkid, libblkid, uuid mount) udisks, palimpsest; File system label (nilfs-tune)
In normal use, Btrfs is mostly self-healing and can recover from broken root trees at mount time, thanks to making periodic data flushes to permanent storage, by default every 30 seconds. Thus, isolated errors will cause a maximum of 30 seconds of filesystem changes to be lost at the next mount. [ 77 ]
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
Many Linux distributions make ISO images available for burning to CD or DVD. While open source operating systems can be used for free, some commercial software, such as Windows To Go requires a license to use. Many live CDs are used for data recovery, computer forensics, disk imaging, system recovery and malware removal.
