Areca Backup

Areca Backup is an open source application that basically allows you to select a set of files / directories to back-up, choose where and how (as a simple file copy, as a zip archive, …) they will be stored, and configure post-backup actions (like sending backup reports by email or launching custom shell scripts).


Areca Backup Features:

  • Archives compression (Zip & Zip64 format).
  • Archives encryption (AES128 & AES256 encryption algorithms).
  • 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, with AND/OR/NOT logical operators)
  • Incremental, differential and full backup support.
  • Support for delta backup (store only modified parts of your files).
  • Archives merges : You can merge contiguous archives into one single archive to save storage space.
  • 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) are transactional. This 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.

BackupPC is an open source, high-performance, enterprise-grade system for backing up Linux, WinXX and MacOSX PCs and laptops to a server’s disk. BackupPC is highly configurable and easy to install and maintain.


BackupPC Features:

  • A clever pooling scheme minimizes disk storage and disk I/O. Identical files across multiple backups of the same or different PCs are stored only once resulting in substantial savings in disk storage and disk I/O.
  • One example of disk use: 95 laptops with each full backup averaging 3.6GB each, and each incremental averaging about 0.3GB. Storing three weekly full backups and six incremental backups per laptop is around 1200GB of raw data, but because of pooling and compression only 150GB is needed.
  • Optional compression support further reducing disk storage. Since only new files (not already pooled) need to be compressed, there is only a modest impact on CPU time.
  • No client-side software is needed. The standard smb protocol is used to extract backup data on WinXX clients. On linux clients, tar over ssh/rsh/nfs is used to backup the data. With version 2.0.0, rsync is also supported on any client that has rsync or rysncd.
  • A powerful web (http/cgi) user interface allows administrators to view log files, configuration, current status and allows users to initiate and cancel backups and browse and restore files from backups.
  • A full set of restore options is supported, including direct restore (via smbclient, tar, or rsync/rsyncd) or downloading a zip or tar file.
  • Supports mobile environments where laptops are only intermittently connected to the network and have dynamic IP addresses (DHCP).
  • Flexible configuration parameters allow multiple backups to be performed in parallel, specification of which shares to backup, which directories to backup or not backup, various schedules for full and incremental backups, schedules for email reminders to users and so on. Configuration parameters can be set system-wide or also on a per-PC basis.
  • Users are sent periodic email reminders if their PC has not recently been backed up. Email content, timing and policies are configurable.
  • Tested on Linux, Freenix and Solaris hosts, and Linux, Win95, Win98, Win2000 and WinXP clients.
  • Detailed documentation.
  • Open Source hosted by SourceForge and freely availble under GPL.
