This backup method creates a backup of the entire repository, including any applications deployed under it, such as AEM. The backup includes content, version history, configuration, software, hotfixes, custom applications, log files, search indexes, and so on. If you are using clustering and if the shared folder is a subdirectory of crx-quickstart (either physically, or using a softlink), the shared directory is also backed up.
You can restore the entire repository (and any applications) at a later point.
This method operates as a "hot" or "online" backup so it can be performed while the repository is running. Therefore the repository is usable while the backup is running. This method works for the default, Tar storage based, repository instances.
When creating a backup, you have the following options:
- Backing up to a directory using AEM's integrated backup tool.
- Backing up to a directory using a filesystem snapshot
In any case, the backup creates an image (or snapshot) of the repository. Then the systems backup agent should take care to actually transfer this image to a dedicated backup system (tape drive).
