Subject Datastore + Fault Tolerant + BundleCache settings
Date Tue, 05 Aug 2008 13:04:41 GMT
Hi all,

We currently store BLOBs in the database and are considering migrating to
file-based DataStore (for various reasons).


Assuming a configuration of 2 linux servers running clustered JackRabbit
instances. The datastore would be configured to reference a SAN or shared
NFS. Assuming a cheaper NFS mount, this raised the following questions:


1)      is it reasonable to rsync the NFS mount to a backup server regularly
to provide fault tolerance?

2)      following on from 1), if we only rsynced the NFS mount every 15 mins
what would be the impact of data loss within the Data Store? 

3)      Finally, does JackRabbit still create local cached bin*.tmp files
when using the DataStore (as it does where BLOBs are in the database)?
(Hopefully not).
