Backup Job Types

JetBackup can perform several types of backups. We will explain briefly about each one of them.

  • Directories - Copy server files/folders that you choose to include.
  • Databases - Databases are regenerated and synced to the destination. Each job run will add the disk usage of each database dump file to the backup. Only supports compressed backup structure.
  • Replicate - Copy files/folders "as is". Only supports incremental backup structure.

What's the difference between "Directories incremental" and "Replicate"?

The "Directories incremental" job will back up the files keeping a "snapshots" based files structure, so you can have several backup retentions of this backup, on supported destinations (SSH / Local / Amazon).

The "Replicate" job, will take the folder "as is", and cannot save backup retentions. Since we are using rsync, the backup process is optimized and only changes from the last full backup will be copied, but you will not be able to have backup retention and to create a "backup history" of your files/folders.

Optimizing your backups on supported destinations.

"Point-In-Time" Space Consuming incremental backups - If you choose more then one backup retention - JetBackup will create a "point-in-time incremental backups", in which will use as little space as possible (using hardlinks). So a 30 days backup retention for a 2GB file/directory will consume 2GB + 30 Days of new/changed files (** At the moment, mysql is fully dumped, as it doesn't support incremental backups).

Supported features:

Backup structure:

  • Incremental - Copy only files (changed or new) since the last full backup.
  • Archived - Copy files to uncompressed archive (.tar file).
  • Compressed - Copy files to compressed archive (.tar.gz file).
