What is UniTree?
UniTree (now known as DiskXtender) is an archival storage system that supports unlimited file size in a UNIX-like file system environment. UniTree manages the file system by automatically migrating files off local disk space onto tape when disk space becomes low or files have not been accessed in a certain length of time. Files that have previously been migrated to tape and purged off disk are automatically cached back to disk on demand. A major benefit of UniTree is that it looks and feels like a UNIX file system. The FTP interface allows you to manipulate files and directories using standard UNIX commands and I/O libraries. This FAQ assumes that you are familiar with normal UNIX file operations such as listing and changing directories and moving and removing files.
