Switching from cold to hot backup

mpw — Wed, 04 Feb 2015 08:15:39 GMT

Hello,I used to do cold backups, as it was easier to configure. But the alfresco-data has serveral GB now and the down time has become quite long. So I want to switch to hot backups.I'm a little scared to do something wrong. Ofc I read the Wiki:https://wiki.alfresco.com/wiki/Backup_and_Restore#Hot_B

Hi,

Lucene indexes backup is created every night by an Alfresco job. If you're hot backup doesn't include indexes backup, you'll have to fully reindex the Alfresco repository when restoring. That can be very long. If you restore indexes backup, at startup, Alfresco will only index transactions done between the index backup and your hot backup.
I always use a dump to backup my database and I don't know if there is a smarter way to do that.
Your database backup has to be done before the Alfresco filesytem backup. Alfresco has no problem with file of the filesystem having no reference in the database. But database records pointing to files that are not existing in the filesystem are problematic.

Thanks for your reply.

So all I have to do is:

- Assuring that Alfresco creates that index regularly
- Not stopping tomcat before a backup anymore

That sounds easier than that wiki article describes it.

Thank you!
