Automatic Backup Plugin

Java class implementation:

com.orientechnologies.orient.server.handler.OAutomaticBackup

Introduction

Configure an automatic backup of databases. This task is configured as a Server handler. The task can be configured in easy way by changing parameters:

  • enabled: true to turn on, false (default) is turned off
  • delay: delay time. You can use different suffixes to specify different measures:
    • ms for milliseconds. Example 10000ms means 10 seconds
    • s for seconds. Example 10s means 10 seconds
    • m for minutes. Example 5m means 5 minutes
    • h for hours. Example 24h means every day
    • d for days. Example 1d means every day
  • firsttime time of first backup schedule. It's referring at current day. The format is: HH:mm:ss. GMT timezone is used.
  • target.directory: target directory, the default is "backup"
  • target.fileName: target file name configurable using the following variables between ${}:
    • ${DBNAME}, as the database name
    • ${DATE}, as the current date following the format. For the complete syntax look at Java DateTime syntax
  • db.include: database list to include. If empty means all the databases
  • db.exclude: database list to exclude
  • bufferSize: In memory buffer size to use in compression. Default is 1MB. Bigger means faster backup but more RAM used (Since 1.7)
  • compressionLevel: Compression level of the resulting ZIP file. Default is maximum: 9. Set it lower if backup takes too much time (Since 1.7)

Default configuration in orientdb-server-config.xml
