fsck -- for Linux file systems

zpool scrub -- for ZFS pools and file systems

ddrescue -- to copy out blocks of a failing device

It has been too long since I used tools for recovering deleted files.


I suggest that your put your data onto a reliable storage platform. 
Choices including buying and configuring a network attached storage 
(NAS) appliance, installing and configuring a NAS operating system 
distribution on the hardware of your choosing, and building a file 
server using the hardware and software of your choosing.  This list 
would be most helpful for the third choice using Debian.


Next, I suggest that your implement disaster preparedness -- backups of 
data and OS configuration settings, images of operating system disks, 
and archives of the prior two.  Keep your backups, archives, and images 
off-line when not in use.  Keep some portion of your media off-site 
(e.g. rotate media on a schedule).
