Short collection of backup scripts. Mostly on bash

Backup Scripts

Collection of backup scripts (sometimes just wrapers) for MySQL. Tools to enhance the MySQL Backup experience and make it easier (almost plug and play...almost!)

All the scripts take care of the retention policy (defined by the user), as followed:

• For MyDumper: User will define weekly and daily retention times.
• For Mysqldump: User will define weekly and daily retention times.
• For Mysqlbinlog: User will define number of days that the binlog files will be keep it
• For XtraBackup: User will define weekly and daily retention times.

Binlog backup

pull-binlogs.sh Bash script for backup binlogs using the mysqlbinlog utility that comes with MySQL 5.6. To launch this script, run:

  nohup ./pull_binlog.sh > /var/log/mysql/pull_binlog.log 2>&1 /dev/null

MyDumper backup

mydumper.sh Bash script used as a wraper of the MyDumper backup tool. Run this script as a daily cronjob

Mysqldump backup

mysqldump.sh Bash script used as a wraper of the classic mysqldump backup tool. Run this script as a daily cronjob

XtraBackup script.

xtrabackup.sh Bash script used as a wrapper of the Percona XtraBackup tool. Run this script as a daily cronjob. It only takes care of full backups. Coming soon: Incremental backups

backup-scripts's Issues

[ERROR] Failed execution. Couldn't execute MyDumper.

I've been using your MyDumper script for a couple of years now, and i'm very happy with it.
A couple of days ago, probably due to an update of mydumper, i started receiving error messages from my cron job, though.

The backups look fine like before, but there seems to be an issue with the exit code. The last lines when running is with a verbose shell look like this:

+ logInfo '[OK] Found '\''mydumper'\'' bin'
++ date +%y%m%d-%H:%M:%S
+ echo '[170427-12:38:54] [OK] Found '\''mydumper'\'' bin'
+ logInfo '[Info] Dumping data with MyDumper.....start'
++ date +%y%m%d-%H:%M:%S
