Nilesh Singh created SOLR-10777:
-----------------------------------
Summary: Replication Backup creation fails with NPE, while
deleting the old backups
Key: SOLR-10777
URL: https://issues.apache.org/jira/browse/SOLR-10777
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: Backup/Restore, replication (java)
Affects Versions: 6.5.1, 6.2.1
Reporter: Nilesh Singh
Priority: Minor
in Solr back up SnapShooter will try to delete the old backups saved on the
disk automatically, but deletion fails as the files may not be the pattern type
expected by the OldBackUpDirectory.
```
private static final Pattern dirNamePattern =
Pattern.compile("^snapshot[.](.*)$");
```
In this case the following code throws NPE.
```
if (obd.getTimestamp().isPresent()) {
dirs.add(obd);
}
```
also in OldBackUpDirectory`s pattern match should haver matcher.matches(), to
fetch the group(1) value.
