> 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 thread|http://mail-archives.apache.org/mod_mbox/lucene-dev/202012.mbox/%3cCAPCX2-LRxHMs55Mx249sSYLPWT-vb-fi=HifRoA12wiwLiSQMQ@mail.gmail.com%3e] for more details.
