AEM data backup

[ariesyinn]

Hi all.

Would replacing the whole /crx-quickstart folder from one instance to another instance include all data including user changes + log?

Thanks.

@ariesyinn  Yes it will. crx-quickstart contains the data store and the node store with all the repository information including versions and logs. However, it's a recommended way to back up a repository. It is recommended to go with online and offline backups

Hi @shelly-goel I see 'make a snapshot backup' in offline backup step 2. Does it mean to snapshot which folder?

[shelly-goel]

Yes it would be the crx repository installation directlry, however it involve downtime ans you would have to plan accordingly. Online backups doesn't have downtime.

Thank you. @shelly-goel. We would back up the data during downtime because afraid we would miss any changes/data coming in after online back up..

@ariesyinn 
After taking the backup by the recommended way mentioned by @shelly-goel , an important point to remember while using the back copy at another place that there should not be any packages inside /crx-quickstart/install or the location of AEM installation director should have the same path otherwise you will end up with corrupted repository or missing data.

For example:

Source path of taking backup is c:/aem/author/crx-quickstart/install

then target path to another machine should be the same c:/aem/author

Because at the time of aem start, package manager tries to validate all the packages either directly uploaded to pack manager or packages kept/removed inside /crx-quickstart/install folder. So if the pack manager found that packages path c:/aem/author/crx-quickstart/install is changed to something else then uninstall of these packages inside /crx-quickstart/install will be triggered.

Hi @BrijeshYadav, currently, there is org.apache.flexi.http.jetty-x.x.x.jar inside /crx-quickstart/install folder and noted that I will remove that jar before replacing /crx-quickstart folder under new server.

In your last paragraph, what does 'packages kept/removed'? Would you mind to elaborate more?

[BrijeshYadav]

Few people use auto installation of aem packages using

[BrijeshYadav]

For the statement "packages kept/removed inside /crx-quickstart/install folder". I meant if any package inside the install folder was added.
Here is the documentation of automatically installing aem package at the time of start which is also known as file-based upload and install

As we have more than one publish servers, can we use that same crx-quickstart folder on any servers or we must use the exactly the same package what I copied.. Let say there will be Author_backup, Publisher_1_backup, Publisher_2_backup and Publisher_3backup.
