solr | backup and restoration
Hi,
We are using solr 4.8.1 in production and want to create backups at runtime. As per the reference guide, we can create backup using something like this:
http://localhost:8983/solr/myCore/replication?command=backup&location=/tmp/myBackup&numberToKeep=1
and we verified that some file are getting created in /tmp/myBackup directory. The issue that we are facing is, how to restore everything using this backup.
Admin guide does talk about "Merging Indexes" using two methods:
a. indexDir for example,
http://localhost:8983/solr/admin/cores?action=mergeindexes&core=core0&indexDir=/home/solr/core1/data/index&
indexDir=/home/solr/core2/data/index
b. srcCore for example,
http://localhost:8983/solr/admin/cores?action=mergeindexes&core=core0&srcCore=core1&srcCore=core2
these are not working in our case as, we want entire data should also be back there for example, if we want to re-create core from a snapshot. I do see there is such functionality available in later versions as, described here

Hi Prateek,
To me it feels like the backup/restore is still an open item should be
higher on the agenda.
Yes, there are work-arounds like copying data from/into the index folder
but this doesn' t seem very stable.
I'm using the following approach in solrcloud since I ran into an issue
with restoring the same backup multiple times:
rm $SOLRDATA_LOCATION/$INDEXNAME/data/index.properties
rm -rf $SOLRDATA_LOCATION/$INDEXNAME/data/restore.snapshot.....
curl "
http://localhost:8983/solr/$INDEXNAME/replication?command=restore&location=$BACKUP_LOCATION&name=$INDEXNAME.$TIMESTAMP
"
Though this is working, I still think it should work with a simple restore
command and no need to tweak the current core/index directory/files.
Met vriendelijke groet / Kind regards,

Manually copying files under index directory fixed the issue.
