Pug - The Cloud File Archiver
Pug is automated backup software designed for use on Linux that allows one to backup files on a server to cloud storage, compressing and encrypting each file individually before uploading. It was designed with the needs of IT professionals in mind, where one may have one or more servers or NAS devices that need to be continually backed up.
Unlike other backup solutions that require use of external physical storage and backing up the same data over and over again, Pug works incrementally. As new files are created or as files change, Pug pushes them into the cloud. Only new or changed files are backed up and every version (or as many versions as you specify) is maintained in the cloud, any one of which may be immediately accessed. Further, Pug is smart enough to recognize that two files are identical and only archives a single copy of a file in cloud storage, thus reducing storage costs.
Pug uses Amazon S3 for cloud storage, though the software is designed so that changes can easily be made to support other cloud storage services.
You tell Pug what locations to archive, which could be local filesystem files or file systems mounted using NFS or CIFS. Pug will scan those locations periodically (on an interval you specify) looking for any new and modified files. Once Pug finds a new or modified file, it will:
