Hi, everyone. This is first my post in dev.to and my first time for write article in second language. today I want to share some trick for backup your database from docker container. let's begin... :)
Note I assume your already running container.
1. Write T-SQL for backup your database.
For example I use TutorialDB database for demonstrate purpose. Your can create same database click Create a database
PRINT "Start Backup process...";
DECLARE @MyFileName varchar(200)
SELECT @MyFileName=N'/tmp/Backup_' + convert(nvarchar(20),GetDate(),112)+'_'+convert(nvarchar(20),GetDate(),108)+ '.bak'
BACKUP DATABASE [TutorialDB] TO DISK=@MyFileName
PRINT "Finished backup process...";
Then save above T-SQL to backup-database.sql
2. Copy backup-database.sql file to your container.
For example I just copy it to tmp directory. You can copy it to any your directory.
Then go inside container and see in tmp directory as below
3. Update packages list to new version.
Go inside your container by docker exec cli as below
Note You need to use --user root (option) for update package list.
Now, update package list by apt-get update -y as below
Then you will installing 2 package such as vim and cron as below
4. Add sqlcmd cli to crontab by cron -e cli as below
For example above configuration is running backup-database.sql every 1 minute. Keep in mind it's just example for show how it work. Next you want to restart crontab for start your schedule job like this
5. see log by tail -f /tmp/daily-backup.log & .bak files.
Until we meet again. Thank you
