Backup not working

[vrindavda <vr...@gmail.com>]

Hello,

I am trying to backup the Solr index data using collection API.

I have \collection2_shard1_replica1\data\index\segments_6 in my data folder,
but when I try to backup files, It expects
\collection2_shard1_replica1\data\index\segments_5 which is not there in
data folder, hence giving exception.

Now when I reindex, I have segments_7 instead of segments_6. But at this
time Backup API is expecting segments_6.

Please help.

Here is exception that I get :

Re: Backup not working

[vrindavda <vr...@gmail.com>]

I realized that Segments_1 is getting created in Shard2 and Segments_2 in
Shard1.

Backup API is looking for Segments_1 in Shard1. Please correct if I have
configured something wrongly. I have created collection using collection API
and am using data_driven_schema_configs configs.
