Version numbers changing

Backuper-X.Y.Z(A)

• X - Changing X number means some breaking changes without backward compatibility. This means that before switching to this version you should check the Incompatible version changes paragraph
• Y - Changing Y number means that the version contains significant changes with backward compatibility
• Z - Changing Z number means that the version contains minor changes or improvements with backward compatibility
• A - Changing A number means that the version contains bugfixes or security/stability improvements. Usually these are hotfixes

Incompatible version changes

1.x.x - 2.x.x

• Fully changed permission system. Check the Permissions section to see the changes
• Fully changed command naming. Check the Commands section to see changes

2.x.x - 3.x.x

• Changed permission system. Now there are different permissions for different storages
• You need to specify the storage when using the /backuper backup command (/backuper backup <storage>)

Basic setup

Use plugins/Backuper/config.yml to configure plugin

1. Automatic backups are enabled by default. To change backup interval change backup.backupPeriod option. To disable automatic backups change backup.autoBackup option
2. If you want to make your backups one time a day at specific time change backup.backupTime option
3. If you want to restart your server after automatic backup use backup.afterBackup option
4. To set the maximum number of backups to store change local.maxBackupsNumber/ftp.maxBackupsNumber/sftp.maxBackupsNumber
5. To set the maximum weight of backups to store change local.maxBackupsWeight/ftp.maxBackupsWeight/sftp.maxBackupsWeight

To setup FTP/SFTP storage check the Configuration section below

To configure the plugin, it is best to look at the full Configuration section, there are many useful options there

Configuration

Backup settings

• Auto backup - (true/false) - Enables automatic backups once at a specified interval (when disabled, backups will only run on the /backuper backup command)

• Backup File Name Format - (Date Time format) - Set a format for backup file names (see java.time docs). It must contain information about both time and date

• Add directory to backup - (List of paths) - Full directory paths to folders/files that you want to be backed up. World folders will be backed up automatically, so you do not need to specify world folders there (For example you can specify "plugins", "config")

• Exclude Directory From Backup - (List of paths) - Full directory paths to folders/files that you want to be excluded from backup. If you want to backup everything from the folder1 except some folder1/file1 you can specify folder1 in addDirectoryToBackup and folder1/file1 in excludeDirectoryFromBackup. (The backupsFolder directory will be excluded automatically to prevent the loop)

• Backup period - (>= 1 Minutes or -1) - The period after which the server will make automatic backups (To change this value you need to set backupTime to -1 and autoBackup to true)

• backup time - (0 - 23 or -1) - Fixed backup time. Automatic backups will be made at this time every day. (backupPeriod will be automatically set to 24 hours). -1 to disable backup time fixation

• Delete broken backups - (true/false) - Sometimes errors may occur while creating a backup. When this option is enabled, such backups will be deleted

• Skip duplicate backup - (true/false) - Backup will only occur if the world has been changed since the last backup. If the world has not been changed, this backup cycle will be skipped. AfterBackup will be executed anyway

• After backup - (NOTHING/STOP/RESTART) - What will the server do after an automatic backup

• Set worlds read only - (true/false) - (True recommended) The backuper will mark all world folders as Read Only to prevent folder changing that may cause the backup crash. True value may cause access denied errors during the backup (you should just ignore that)

Local storage settings

• Enabled - (true/false) - Enable local storage to use it via the Backuper

• Auto Backup - (true/false) - With automatic backup, backups will be saved to specified local storage. Works only if local.enabled: true and backup.autoBackup: true

• Max backup weight - (>= 1 or 0) - Maximum weight of backups that will be stored in local storage (MB) (0 - unlimited)

• Zip archive - (true/false) - Do you want to store backups in ZIP archives in local storage?

• Zip compression level - (0 - 9) - archive compression level. A higher value may reduce file size, but may also increase the time required to archive and decompress

FTP storage settings

• Enabled - (true/false) - Enable FTP storage to use it via the Backuper

• Auto Backup - (true/false) - With automatic backup, backups will be saved to specified FTP server. Works only if ftp.enabled: true and backup.autoBackup: true

• Backups folder - (Path) - FTP server directory where backups will be stored

• Path separator symbol - (Symbol) - Path separator symbol used on FTP SERVER. For example / on UNIX systems and \ on windows

• Max backups number - (>= 1 or 0) - Maximum number of backups to be kept on FTP server (0 - unlimited)

• Max backup weight - (>= 1 or 0) - Maximum weight of backups that will be stored on FTP server (MB) (0 - unlimited)

• ZIP archive - (true/false) - Do you want to store backups in ZIP archives on FTP server?

• ZIP compression level - (0 - 9) - archive compression level. A higher value may reduce file size, but may also increase the time required to archive and decompress

SFTP storage settings

Notes

• Please report any issues to GitHub
• RESTART option may not work well, so it's better to use STOP with a loop in your start script (start script auto restart ON)
• You can reset the backup time if it is broken and your backup.backupTime is set to -1 by changing lastBackup to 0. Then the next backup will happen at the server start and the next ones will happen after backup.backupPeriod
