Document storage design (backup and restore)

Firstly, we are not currently using Alfresco. Our evaluation version of the latest beta of v3 does not work at all (but that is off topic).We currently have over 1.3 million documents, nearly all 30kB to 80kB in size. Our main problem is that we use a tape backup solution. Given the volume of dat

Just a quick points.
No it would not be a good idea to restart alfresco prior to restoring the document store, restore of alfresco requires the document store to be done before the DB (I think.)

Could you have a hot standby disk that is periodically (say every few minutes) updated with the change set. Then if disaster strikes switch to that standby disk? That would be quicker than restore from tape. And your tape backups can then just be en extra layer in your long term off-line backup. One thing to be aware of is that the data in the content store is fairly static. So even if you have 55GB of data, only a small fraction of that data will be new.

I'm sure Administrators will be able to give fuller answers.

Thanks for your response. It would have been my guess that the indexes would be a bit unhappy about being restored without data too.

The problem/issue with disaster recovery is that you have to assume that any backup on-site is not accessible. This could be due to fire, flood, etc. and worse still, the problem can be with one of your neighbours.

I know that tape back up is not ideal and server replication off-site is the way to go but we all have budgets to stick to.
