Ubuntu – Easy database tool (the more gui the better)

There is the LDAP Administration Tool , available from the repositories.

There is also the GQ LDAP Client , but it's a bit older and (I'm going to be blunt) not as good. :)

I don't think there's an existing solution that offers exactly what you describe. You would have to write a couple of scripts, starting with something like fsniper that watches for new files and then triggering the addition of this file to a text file tracking all files, copying the file to the harddisk, complaining if the disk is full etc. It is of course feasible, but involves a lot of work and has a lot of pitfalls that existing backup solutions take care of coping with (e.g. handling a crash during the copy of a file).

Another solution (that does not store plain files on the disk and does not allow any nice thumbnail preview) is using a powerful backup solution like bacula , that is built for enterprise grade backups and can cope with backing up to multiple tape drives. You can then adapt such a solution to use harddrives instead of tape drives, as explained here on the bacula wiki

A software that might be useful for your current workflow (manual copying of new files) is “Virtual Volumes View” (short: VVV):

VVV is an application that catalogs the content of removable volumes like CD and DVD disks for off-line searching. Folders and files can also be arranged in a single, virtual file system. Each folder of this virtual file system can contain files from many disks so you can arrange your data in a simple and logical way.

Unfortunately it's not available in the repositories but has to be compiled from source.
