chef-backup

Simple backup scripts to do daily backups of an open source chef server (and to do disaster recovery on a new chef server)

Usage

Perform a daily backup (add to your crontab): chef-daily-backup BACKUP_DIR RETENTION_DAYS

Restore a daily backup: chef-restore-from-backup BACKUP_DIR BACKUP_DATE(YYYY-MM-DD)

Examples

chef-daily-backup /chef-backups 10

Creates backups of the database, uploaded cookbooks, and basic .pem files (webui.pem and validation.pem) that can be used to restore your chef environment on a newly built chef server. The backups are stored in /chef-backups (which must already exist). Any backups in /chef-backups older than 10 days will be deleted after the current backup finishes.

chef-restore-from-backup /chef-backups 2013-03-19

A warning is displayed asking if you really want to overwrite the current data on your chef server. If you choose to continue, /chef-backups will be checked to see if it contains all the necessary backups (created via chef-daily-backup). If everything's good, the script continues to tear down the existing chef environment, expand the backup for March 19th, 2013, and restart chef services.

Notes

Currently this only works for chef 10.x, which uses couchdb to store data.

The restore script makes some assumptions about your setup (location of various directories, existance of the chef-webui user). Most of these can be found in constants at the top of the file. Please review before use.

Systems

These scripts were written for Ubuntu systems. Patches and/or pull requests for compatibility with other systems are more than welcome.
