ZixFS is a simple embedded file storage based on a Zip file structure. It has been developed as an alternative to GridFS, but is still not on par with it. The main objective is to provide a powerful filesystem under a Windows 32-bit environment, with the capability of handling terabytes of data, which is not offered by GridFS. The original ZipStorer class library was developed Jaime Olivares.
Vault is a Perl script to store away files, including metadata and integrity checks. Any file you want to keep, you put into a vault. This vault is just a directory. You can create any directory hierarchy allowed by your filesystem, and when you "vault" a file to a destination directory, a subdirectory is also created to store metadata files containing the MD5 hash of the file, the date it was vaulted, and any notes (i.e., metadata) you want to save regarding the file.
