> Backup API
> (https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-backup)
> fails with exception:
> "org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
> Could not backup all replicas"
> Steps to reproduce the issue
> Solr 6.6.0 (fresh install, 4 node solr cluster):
> 1. Create a collection in Solr called citibike:
> {color:#14892c}http://localhost:8983/solr/admin/collections?action=CREATE&name=citibike&numShards=2&replicationFactor=1&maxShardsPerNode=1&collection.configName=rohit&&createNodeSet=192.168.3.15:7574_solr,192.168.3.15:8983_solr{color}
> 2. Index 8 documents to Solr collection citibike:
> {
> "responseHeader":{
> "zkConnected":true,
> "status":0,
> "QTime":10,
> "params":{
> "q":"*:*",
> "indent":"on",
> "wt":"json"}},
>
> {color:#14892c}"response":{"numFound":8,"start":0,"maxScore":1.0,"docs":[{color}
> {
> "id":"doc1",
> "_version_":1570643322182041600},
> {
> "id":"doc2",
> "_version_":1570643322185187328},
> {
> "id":"doc3",
> "_version_":1570643322185187329},
> {
> "id":"doc5",
> "_version_":1570643322188333056},
> {
> "id":"doc6",
> "_version_":1570643322191478784},
> {
> "id":"doc7",
> "_version_":1570643322191478785},
> {
> "id":"doc8",
> "_version_":1570643322191478786},
> {
> "id":"doc4",
> "_version_":1570643322179944448}]
> }}
> 2. Try to create a backup of the collection with only 8 documents:
> {
> "responseHeader":{
> "status":500,
> "QTime":20},
> {color:#14892c} "failure":{
>

> *Suggested Fix: * _{color:#205081}Call commit on the collection and try to
> execute the Backup API again. This time it works as the segments have been
> written to disk.
> So fix would be to call commit for the collection intrinsically every time
> BACKUP API is invoked. {color}_
