How long should a backup take?

I did a backup yesterday of AEM 6.2, a simple AEM quickstart. Through the JMX interface:

URL: http://localhost:4502/system/console/jmx/com.adobe.granite%3Atype%3DRepository (startBackup(java.lang.String target))

I was watching the backup progress before leaving for the day using:

http://localhost:4502/libs/granite/backup/content/admin.html

It was at 20% around 3:30 pm EST. I came in this morning, and it showed that it had completed at 23:26:16 EST

Question: Should I expect 8 hrs for a backup?

Question: Should I expect more than 8 hours?

Question: What should I be telling my customer? (Immigration, Refugees and Citizenship Canada)

Thanks

P.S. It did appear to work. I was able to unzip it and use it.

Hi 

As mentioned by Runal,

You might be doing online backup which talk more time as compare to offline.

Documentation says that in Offline Backup, a snapshot backup usually takes only a few seconds, the entire downtime is less than a few minutes.

Please read the documentation which explain both process in details.

Doc:-  https://docs.adobe.com/docs/en/aem/6-2/administer/content/backup-and-restore.html

According to the docs -- 

https://docs.adobe.com/docs/en/aem/6-2/administer/content/backup-and-restore.html

It depends on the size of the JCR.

I guess you triggered online backup which is supposed to take more time as compared to offline backup.

If you have luxury to stop the server then offline backup will be lot faster, its more like a snapshot backup.

Please go through the link that Scott shared, it will give you more details around the type of backup supported.

As mentioned by others in the thread already, if you can share the size of repository, it can be validated whether 8 Hrs is good enough or not due to the dependency.

Also if you have a slave standby available, you can bring down the slave to take the offline backup, as that would be equal to a snapshot without the need of impacting the live author instance.

Thanks very much. I will research the offline option and present that to the client.

Looking at https://docs.adobe.com/docs/en/aem/6-2/administer/content/backup-and-restore.html#Filesystem Snapshot Backup

> Do a snapshot of the filesystem AEM is deployed on.

Is this simply cloning the directory?

I'm in Windows 7.

Yes. Snapshot backup is indeed cloning/copying your entire crx-quickstart folder.
