A new tool designed to provide a workflow around hashing files and then checking them later in order to find corruption. Combined with external backup solutions (such as CrashPlan or Amazon Cloud) this tool lets you forgo heavier tools like SnapRaid which require dedicated drives. This doesn’t provide recovery of data. Only corruption detection.
There is a lot of information scattered throughout the internet about creating backups of files, filesystems, hard drives, solid state drives, etc. However, there is really no one place where the different methods and technologies are described, compared, and packaged as full stack solutions. Recovery is almost a black art. Random tools you find talked about on miscellaneous forums.
Rather than using a wiki which can get messy I’ve created a git repo of Markdown files which try to walk through different backup solutions, end to end. From describing what they are to how to recover and maintain them.
I’ve started with a document on using mergerfs, snapraid, and CrashPlan given that’s my setup. Should be noted that I’m the author of mergerfs.
Pull requests are very, very welcome. All any any tech, platforms, setups are welcome.
