Free to create an automated system recovery set using backup software for linux

Crash Recovery for Linux sounds a bit superfluous. Linux is regarded as one of todays most stable Operating Systems. In the case of some hardware failure like a broken disk it can however be handy.
Of course your machine doesnt have to have linux installed to make use of the CRK kit. There are several uses and purposes for the CRK to be used. To name a few :
- recovery of a trashed LILO boot record. How many times does it happen that some person installs windows 98/95 after he/she installed linux? Well in that case windows 9X just overwrites the MBR record and linux wont be able to boot anymore.
- backup over the network in the form of tar.gz tarballs. Both FAT16, FAT32, ext2 and all filesystems which Linux supports in a read/write fashion can be taken care of. The strong part of the CRK is when a disk is replaced or repartitioning is being done. The CRK boots a complete mini linux with networking where all possible hardware which is inside the Linux kernel is available.
- Testing hardware of new intel based machines.
- Detecting versions and types of hardware. The Linux kernel holds a large database of hardware supported. Booting a linux kernel doesnt only resolve if the hardware is ok, it also show its specs. This can be handy if one wants to check-out an old/new PC which is for sale.
- Recovery of a misconfigured or hacked Linux system. Well that can happen. /etc/fstab can be wrong or the root password is unknown etc.
- make a tape backup of a disk which cant be booted anymore.
The CRK is based on RedHat Linux. I have always used RedHat systems, thats why. When my system needed maintenance the rescue floppy image which RedHat supplies didnt fullfill my needs.
Thats why i created the CRK. Lately i use Mandrake. How and why the CRK was created read the short history. The CRK is licensed under the GNU Public License (GPL).

Since MySQL is the most popular SQL server that is used in conjunction with web sites, there was a need for incremental backup utility. ZZEE Active SQL Backup is designed for clients of web hosting companies, and can be useful to system administrators as well.
Main features:
- Can perform *incremental* backup of MySQL database
- Can perform full backup of MySQL database
- Can replicate database
- Can process SQL queries
- Can dump database structure
- Can suggest database changes needed to process incremental backup
- Can send data backed up by email
- Can transfer backed up data by FTP to other computer (if Net::FTP is installed)
- Can compress backed up data
Usage synopsis
Active SQL Backup can do incremental or full backups of MySQL database as often as needed. It is suitable both for the clients of web hosting companies who can not get access to MySQL update logs and for the host administrators. Backup syntax is:
shell> ./zmdb.pl -b
It stores backup files in BACKUP_DIR, specified in user_settings.txt, named like YYYY_MM_DD_hh_mm_ss.sql[.gz]. The backup files consist of series of SQL INSERT statements and may contain DELETE statements. The database scheme is stored in file database_name.create.sql. If gzip is available, then Active SQL Backup automatically uses it to compress stored data. The program can automatically send backed up files by email or upload to the other computer by FTP.
If the system fails, Active SQL Backup can restore the database. Restore syntax for incremental backups is:
shell> ./zmdb.pl -r
If you make full backups, restore syntax is the following:
shell> ./zmdb.pl -e < BACKUP_DIR/database_name.create.sql
shell> ./zmdb.pl -e < BACKUP_DIR/YYYY_MM_DD_hh_mm_ss.sql &
The first line is needed to restore database structure, and the second is the *most recent* data file. You may need to "gunzip" it before supplying to restore.
You can use the program to dump database structure
shell> ./zmdb.pl -s > structure_dump_file
or to process queries. The latter feature is useful if you need to process queries regularly, for example, to update membership status of the users of your online service. The syntax to execute SQL queries is:
shell> ./zmdb.pl -e < some_sql_file
Where format of some_sql_file is the same as with Mysql utility: SQL statements are separated by semicolon. Note that if you pass SELECT queries to Active SQL Backup, then no result will be returned.
Syntax summary is:
zmdb.pl [SINGLE_OPTION]
-a --advice suggest database modifications and tables_config.txt
-b --backup backup database structure and data
-e --execute execute SQL queries [from STDIN]
-h --help print this screen
-r --restore restore database structure and data
-s --structure dump database structure [to STDOUT]

Automated Revision Control System is used to automatically monitor remote and local git, subversion, CVS, and even rsync repositories.
It notices changes and updates the local and remote repositories almost automatically. It requires either git, subversion, rsync, or CVS, and can be used for Web site maintainance, backup, communications, and many other purposes.
Enhancements:
- This release generally works a lot better to the extent that the authors are starting to using it for everyday file syncing and backup.

ESR Backup is a simple easy to use backup system for UNIX and Linux. It provides a simple, easy to configure solution for file system integrity.
ESR Backup project works on an automatic 2 week cycle to assure you have an easy to recover system.
Main features:
- Simple and easy to configure
- Automatic 2 Week File Rotation Management
- Remote Storage via FTP
- Local File Storage

- Completely FREE to use
ESR Backup takes the complication out of daily back ups, it does all the work for you so you can concentrate on more interesting things. ESR Backup automatically performs regular Full and Incremental backups on the following schedule
Monday - Full Backup
Tuesday - Incremental Backup
Wednesday - Incremental Backup
Thursday - Incremental Backup
Friday - Incremental Backup
Saturday - Incremental Backup
Sunday - Full Backup
It maintains 3 directories , current-week, last-week, and weekly-archives. After the full backup is performed on Sunday, it automatically rotates the last full backup from the last-week directory to the weekly-archive for safe keeping. It then removes the other archives because they are no longer needed.
It automatically rotates all archives from the current-week directory to the last-week directory. The current-week directory is then ready to hold next weeks backups. You always maintain 2 complete sets of backups. And all your old archives are ready to be stored on tape or CD or handled any way you choose.
ESR Backup provides you with remote archive storage via FTP so you can maintain current backup sets off site easily. If you dont have access to a remote FTP server , or do not wish to use one. ESR Backup can store archives on the local file system in a directory you choose. You can also encrypt your archives with a 448 bit encryption key.
