Mergerfs alternatives
MergerFS is a user-space union filesystem that allows merging directories of file systems (or parts of them) so that they appear as a single one. It is useful for servers where you have several storage devices (hard disks or USB keys), and you need to organize several large data sets for different clients on a single server. Some of the primary features are fast file system performance, snapshots, and clones that solve the problem of versioning and merging changes into a live filesystem, snapshot replication for a distributed filesystem that can be used as a cloud cache.
It supports different operating systems, such as Linux, Mac OS X, Solaris, and FreeBSD. It can be mounted as one directory from each file system or used transparently within a single OS filesystem. MergerFS is geared towards simplifying the storage and management of files. It aims to be simple, fast, transparent, and non-intrusive. In essence, it provides one take on unified storage, where you can seamlessly move files between Amazon S3, Openstack Swift, Cloud Storage, and other cloud services.
