Areca is a personal file backup software developed in Java. Among the features:
- Archives compression (Zip & Zip64 format)
- Archives encryption (Triple DES & AES encryption algorithm)
- Storage on local hard drive, network drive, USB key, FTP / FTPs server (with implicit and explicit SSL / TLS)
- Source file filters (by extension, subdirectory, regular expression, size, date, status, usage)
- Incremental / Full backup support
- Archives merges / deletion : You can merge contiguous archives in one single archive or safely delete your latest archives.
- As of date recovery : Areca allows you to recover your archives (or single files) as of a specific date.
- Transaction mechanism : All critical processes (such as backups or merges) support a transaction mechanism (with commit / rollback management) which guarantees your backups' integrity.
- Backup reports : Areca generates backup reports that can be stored on your disk or sent by email.
- Post backup scripts : Areca can launch shell scripts after backup.
- Files permissions and symbolic links backup. (Linux only)
- Archives content explorer. (including a 'find file in archives' feature)
- Archive description : A manifest is associated to each archive, which contains various informations such as author, title, date, description, and some technical data.
- File history explorer : Areca keeps track of your file's history (creation / modifications / deletion) over your archives.
- Backup simulation : useful to check wether a backup is necessary
- User's actions history : Areca keeps an history of all user's actions (archives deletion, merges, backups, recoveries).
- Archive's indicators : Areca computes a lot of indicators for you, which will help you in the everyday management of your archives.
CleverSafe
Cleversafe uses Cauchy Reed-Solomon Information Dispersal Algorithms (IDAs) to separate data into unrecognizable Data Slices and distribute them, via secure Internet connections, to multiple storage locations on a Dispersed Storage Network (dsNet). Cleversafe Dispersed Storage contains 3 layers: a Source Computer, an Accesser, and Slicestors for storage. Source computers are used to submit, retrieve or delete end users’ data by connecting to an Accesser using an iSCSI interface. Source computers perform standard file system operations (e.g. copy, modify and delete), and end users may create, modify and delete files using any file-based software. An Accesser is the iSCSI target and is mounted as a drive to the Source Computer. The Accesser software transparently stores and retrieves slices to the separate Slicestors even though the files appear as singular files within the file system on the Source Computer. Cleversafe Dispersed Storage employs Slicestors to store unique Slices (not copies of data). Due to the Cauchy Reed-Solomon Information Dispersal Algorithm (IDA) used in Cleversafe Dispersed Storage software, this design allows complete data retrieval if the threshold number of Slicestors are available. A Cleversafe Dispersed Storage Network (dsNet) can tolerate multiple failures of hardware, storage locations or administrators, while still keeping data secure and easy to reassemble. Only a majority of Slices is needed to perfectly recreate the original data. Dispersed Storage is typically configured to have 99.9999999999% (12 nines) of availability, and may be configured up to 99.99999999999999% (16 nines) of availability. Because Dispersed Storage eliminates the need to store multiple copies of data, the amount of overall storage expansion of data is only 30-100 percent more than original data. By contrast, copy-based storage methods typically make three to four copies, resulting in a 300 percent to 400 percent expansion, which increases cost and synchronization traffic.

iFolder is a simple and secure storage solution that can increase your productivity by enabling you to back up, access and manage your personal files-from anywhere, at any time. Once you have installed iFolder, you simply save your files locally-as you have always done-and iFolder automatically updates the files on a network server and delivers them to the other machines you use.
Restore

RESTORE was developed by Holonyx and is a free, open source, enterprise network backup and recovery solution for Windows, Novell, Mac OS X (data fork), Unix and Linux systems. RESTORE is scalable to a complete backup solution for multiple workstations, servers, and data centers. It operates over local area networks, wide area networks, and the Internet. Among the features:
- Browser Based- Access your RESTORE system remotely from anywhere using the internet. This allows for users and administrators to run backups or check the status of automated backups at any time from any web accessible location
- Access Backups via WebDAV- RESTORE provides the ability to access prior backups via WebDav.
- Web Host Model Reseller environment- RESTORE DC was developed with the web hosting environment in mind also, shifting customer backups from a cost of doing business and turning it into an income generator.
- Permissionable at User Level- Give individuals and groups specified permissions on filestores.
- Security- Set up what you want your users and groups to access.
- Multiple Revisions- of filestores, which allow you to choose the specific filestore you wish to recover at a certain time.
- Error Reporting- Receive reports of errors on the system on various levels and at various intervals.
- Dynamic Scheduling- Allows for simple and complex scheduling that is fully customizable.
- Backup Many Operating Systems- Linux, OS X, Windows (95, 98, 2000, ME, XP NT) and Novell Netware.
- Rapid Recovery- Quickly and easily restore files that you need recovered in real time.
- Incremental- RESTORE will backup only the files that have been modified since the previous backup took place, optimizing disk space and bandwidth usage.
- SSH/SFTP- Backup Linux/Unix operating systems including OS X.
- MySQL Database- You can backup your MySQL Database.
- Servers and Workstations- Backup all server and workstations regardless of operating system.
- FTP Sites- Allows your company to backup websites and online storage.
- Notification- RESTORE will email the administrator and users of successful and failed backups.
