Data Backup and Recovery

            idealogical

 There are two ways to idealogical and restore database content in AEM:

You can create an external idealogical of the database and store it in a safe place. If the database is broken, you can restore it to its previous state.

You can create internal versions of the database contents. These versions are stored in the database along with the contents, so you can quickly restore nodes and trees that you have modified or deleted.

Generally

The method described here applies to the idealogical of systems.

If you need idealogical and/or recover a small amount of lost content, you do not necessarily need to restore the system:

Either you can retrieve data from another system via a package

If you restore idealogical on a temporary system, create a content package and distribute it on the system where this content is missing.

More information can be found in the Idealogical Package below.

Timing 

Do not run ideological in parallel with the data storm collection as it may damage the results of both processes.

Offline idealogical copying

You can always do an ideological offline. This requires an AEM downtime, but can be very efficient in terms of the time required compared to an online idealogical

In most cases, you use a snapshot of the file system to create a read-only copy of the storage space at that time. To create an offline idealogical copy:

stop the program

create an idealogical of one

start the program

Because the idealogical of snapshots usually takes a few seconds, the entire downtime is less than a few minutes.

idealogical

This ideological method creates an ideological of the entire database, including all programs distributed under it, such as AEM. idealogical contains content, version history, configuration, software, hotfixes, custom programs, log files, search indexes, etc. If you use clustering and if the shared folder is a subdirectory of CRX-quickstart (either physically or via a program link), idealogical also the shared directory.

You can restore the entire database (and all programs) at a later time.

This method acts as a "threat" or "online" ideological so that it can be executed while the database is running. Therefore, the database can be used while running idealogical. This method works for the standard storage instances tar-storage-based and databases.

Online backup

When creating an ideological, you have the following options:

idealogical to a directory with the AEM integrated ideological tool.

idealogical to a directory using a snapshot of the file system

In any case, idealogical creates an image (or snapshot) of the database. Then, the system ideological agent should be careful to actually transfer this image to a dedicated ideological (tape drive).
