In case our collection is very large (or there are a few of them) in a case when full replication is needed, Solr can use all the bandwidth of our network (if the disks are fast enough). This is good in some situations, but bad in others. Imagine that you have some collections being queried and of them starts to replicate a tens of gigabytes of data – all the other collections would suffer. Thankfully with the release of Solr 5 we got replication throttling and we can use it to limit the amount of data allowed to be transferred by Solr.

Backing Up Your Index
Did you ever wonder if you can create a backup of your index with the tools available in Solr ? For exmaple after every commit or optimize operation ? Or may you would like to create backups with the HTTP API call ? Lets see what possibilities Solr has to offer.
