backupdir Cookbook

Backup directories by a crontab and do a remote copy

Requirements

Platform

• Debian/Ubuntu
• RHEL/CentOS/Scientific
• Fedora
• ArchLinux
• FreeBSD

Recipes

Critical data of prod envs usually reside in DB or conf files

After we have exported them to files and directories, we need backup them properly

This cookbook enables us to:

• Automate configure a daily cron to do the backup
• Directories will be copied to another local directories, and tar as a package with timestamp attached to the filename
• Do a remote copy for the latest tar file by scp or nfs everyday.
• To avoid local tar files take too much disk capacity, very old tar files will be deleted automatically.

Some files are so critical that we want to do a backup, whenever it changes:

• Setup a crontab which check the file every 5 min
• If the modified time of file is changed, do a backup with timestamp attached to the filename.

• If not changed, do nothing

• default

• backup-dir: Backup directories in the way explained in the info section

• backup-file: Backup critical files in the way explained in the info section

Backup a directory without remote copy

"backupdir": {
  "dir_list": "/data/neo4j;/var/mysql/exported/",
}

Monitor changes to critical files and do the backup

"backupdir": {
  "file_list": "/data/idm/keystore",
}

Backup a directory with scp remote copy

"backupdir": {
  "dir_list": "/data/neo4j;/var/mysql/exported/",
