Free highly configurable backup software for linux

Large Database Backup is a PHP class can be used to backup large MySQL databases into multiple files.

It can list the tables of a given MySQL database and generate SQL statements to create and insert records with the current values of the table rows, as if it was creating a new database. The class stores the generated SQL statements in files.

A full backup process can be split in multiple iterations to not exceed PHP default script execution time limit. Each iteration dumps a limited number of table rows. An iteration can be executed by a script that redirects the page request to itself at the end to proceed to the next iteration.

Simple Backup is a shell script to create basic backups using tar, grep, sed, and bash.

Simple Backup works by using a file that contains the folders to be backed up and a file that contains expressions to exclude certain folders/files.

Usage: backup.sh < backuplist > < excludelist >

Snap Backup automatically puts the current date in the backup file name, alleviating you from the tedious task of renaming your backup file every time you backup. The backup file is a single compressed file that can be read by zip programs such as StuffIt, gzip, and WinZip.

Good system administrators have backup procedures for their company servers, databases, and network files. Individual computer users, on the other hand, are usually left to fend for themselves. Snap Backup is the simple answer for individual users, in the corporation or at home, who want to protect their valuable data.
