Hello,We currently have 2 machines. A master one which handle all requests to our alfresco repository and a "slave" one which should be synchronized every night with master's data.My work is based on this article : http://wiki.alfresco.com/wiki/Backup_and_Restore. I spent a lot of time in experienci

Just to double check, is the 'dir.root' property in the standby instance is pointing to the directory created in step 7?

Also, what value do you have the 'index.recovery.mode' property set to (if any)?

Cheers,
Peter

I double checked too, but my standby configuration is pointing to the right directory. For sure.

Also, what value do you have the 'index.recovery.mode' property set to (if any)?

index.recovery.mode is set to VALIDATE :
index.recovery.mode=VALIDATE in repository.properties file

I don't understand how backup-lucene-indexes could be synchronized with database backup because, backup of lucene indexes and mysql backup is not made at the same time (backup lucenes is made by alfresco at 3am and my routine is 4am). It exists differences between them, no ?
Do you have an idea how long time does backuping lucene indexes take ?

Thank you,
Nicolas Maupu

I finally figure out why I had my problem 🙂

In fact, it was from my rsync command … Some files in alfresco :

backup-lucene-indexes/system/system/IndexInfo
backup-lucene-indexes/system/system/IndexInfoBackup
backup-lucene-indexes/workspace/SpacesStore/IndexInfo
backup-lucene-indexes/workspace/SpacesStore/IndexInfoBackup
backup-lucene-indexes/workspace/lightWeightVersionStore/IndexInfo
backup-lucene-indexes/workspace/lightWeightVersionStore/IndexInfoBackup
backup-lucene-indexes/archive/SpacesStore/IndexInfo
backup-lucene-indexes/archive/SpacesStore/IndexInfoBackup
backup-lucene-indexes/user/alfrescoUserStore/IndexInfo
backup-lucene-indexes/user/alfrescoUserStore/IndexInfoBackup

don't have their date changed, neither their size … So rsync didn't update them on standby server (by default, it checks only size and date to know if file is updated or not) !
I just added –checksum option to rsync to update these files too.
My data synchronization works well now.
