Hello,<p>my name is Chris and I am a german developer looking for feedback on an idea of mine that I would like to develop further.<p>The idea is to blend cloud-based storage space with the local file system in order to transparently expand storage space.<p>This would probably best be done as a file system driver which monitors pre-defined folders on the harddisk for given quotas, eventually transferring files to cloudspace when their surpass the preset quota space for the folder.<p>Once safely transferred (controlled by hash value), the local file would be replaced by a link which can then be resolved upon re-request of the file.<p>The idea is to thereby provide some sort of elastic storage space which only holds the most important/most often requested files locally. Everything else gets transferred to the cloud, thereby providing "unlimited" storage space or at least "greater than your hard disk size".<p>Does such a software already exist?<p>If not, would that be of interest to the community?<p>Thanks for any insight/comment/suggestion.
I think Dropbox/OneDrive have some form of lazy local syncing. As far as I know, though, there is no automated pruning of local copies of the least recently used files, but that sounds like a cool idea.<p>If you just want pure cloud storage that acts like a local disk, Azure File Storage containers are mountable (at least in Windows). I'm sure there is a FUSE driver for other cloud storage providers.
