best practice is to use tools like rsync to sync the alf_data dir while the server is running to the new server or even better to a shared filer to be mounted on the target server (this will avoid that transfer on the next migration). On the first run this may last 8 hours but if you repeat the sync (incl. delete missing on the target) every day after the content cleaner job has run the sync may only last a few minutes or seconds. Once you plan the final migration you just need to sync the day folder in alf_data and to backup/restore the db. Index could be restored from the solr-backup the day before since solr will track the gap once started.
Hello,Is there a way to speed up Alfresco backup and restore.I am copying the alf-data folder to restore it on another server, the problem is that the copy takes at least 8 hours with a size of 300 gb.Thank you
