Document versioning in Liferay and Amazon S3

23/07/2013 Leave a comment

Liferay Portal is an enterprise collaboration platform with document management system. It supports multiple users to have access to the same files. Making a mistake, while editing a file represents a risk for all the users. What if someone deletes an important part of a text? Is it definitely lost? No, it isn’t. We can rely on Liferay’s versioning system to address this concern. But, what if you use an external system as your document management repository (such as Amazon S3) that provides an own versioning capability too? Which versioning you should rely on then? The article below gives some insights to Liferay and Amazon S3 versioning. Read more…

We have been exploring capabilities of integrating Liferay with Amazon’s S3 storage service set for documents library repository. In one of our previous article we have introduced the purpose of integrating Liferay with Amazon S3 and provided basic information on how to setup those 2 systems to talk to each other.

Setup Amazon S3 to Liferay with data migration

24/06/2013 2 comments

We slightly introduced Amazon S3 and its basic integration with a clean Liferay installation in a previous article. What should you do, if you have already uploaded files in Liferay and you want to move them from local storage to Amazon S3? Files that are uploaded to Liferay’s local storage will become inaccessible, if you just perform the steps described in the previous article. That’s because the procedure configures Liferay to use Amazon S3 instead of its local storage without moving files that were originally uploaded to the local storage. Attempts to access those files will result to an Internal Server Error. Is it possible to move these files? Yes, it is. Does data migration affects their settings? No, file settings stay untouched. Here is a short intro on how you can migrate files using the Data Migration Tool. Read more…
