Deduplication
-
Owing to various historical circumstances, such as insufficient
funds to store hardware, lack of a backup system or organized
note-taking for backups, many FRDCSA files have been copied and
copied, into a snowballing collection of files on various hard
drives.
The goal of the project is to backup all of those files,
detecting duplications of individual files as well as whole
directory structures, and backing up each file on enough disks in
enough phyical locaitons so as to minimize the chance of permanent
data loss.
