Short Description
The c42-backup suite is a simple python program for maintaining a central backup in a small, but distributed environment with a central file share. Basically it is a wrapper around the tar backup facility.
The main objectives of c42-backup are:
- Common, simple configuration of backup tasks.
- Use same configuration for full and incremental backups.
- Provide a network wide index of backups.
- Separates creating and compressing of backup files
- Automatically delete outdated backup files.
- The rules which defines if a backup file is outdated or not are specified in the configuration.
- Provide a configuration mechanism that is strong enough to write general backup configurations, which can be shared between different machines and users.
A task is defined backup template. At invocation of the task it is determined if a full or incremental backup should be done.
The separation of creating and compressing of backup files allow the use on a client machine with low CPU resources. For client machines with big CPU resources or a small network bandwidth the compression can be done also on the client side.
Prerequisites
c42-backup depends on following components:
*
- python (2.4)
- Berkly DB
- a POSIX compliant operation system (e.g. Linux)
- GNU Tar command
- Bzip2 Compressor
It is successfully tested under Debian Sarge (i586) and Ubuntu Dapper (amd64).
