> Key: SOLR-15088
> URL: https://issues.apache.org/jira/browse/SOLR-15088
> Project: Solr
> Issue Type: Sub-task
> Reporter: Jason Gerlowski
> Assignee: Jason Gerlowski
> Priority: Major
> Fix For: main (9.0), 8.9
>
>
> Currently backups read and write files (either locally, or across a network),
> but nothing is done to make sure that a backup isn't backing up index files
> that are already corrupted. Or to make sure that corruption doesn't occur in
> transit. Backup/restore should ahve some protections to ensure that files
> that are already corrupted aren't persisted. We can do this by computing a
> checksum of the file as it's being read/written and comparing that to values
> stored in the index files already.
> See
> [SIP-12|https://cwiki.apache.org/confluence/display/SOLR/SIP-12%3A+Incremental+Backup+and+Restore]
> and the corresponding [discussion
