Cant create snapshot life cycle policy

[AClerk]

Hey All,
Trying to create snapshot life cycle policy according to the knowledge article

PUT /_slm/policy/daily-snapshots
{
  "schedule": "0 30 12 * * ?", 
  "name": "snapshot-daily-snap-{now/d}", 
  "repository": "elastic_backup", 
  "config": { 
    "indices": ["monitoring*", "rollup*"], 
    "ignore_unavailable": false,
    "include_global_state": false
  },
  "retention": { 
    "expire_after": "90d"
  }
}

I am getting an error

{
"error": {
 "root_cause": [
   {
     "type": "invalid_index_name_exception",
     "reason": "Invalid index name [_slm], must not start with '_', '-', or '+'",
     "index_uuid": "_na_",
     "index": "_slm"
   }
 ],
 "type": "invalid_index_name_exception",
 "reason": "Invalid index name [_slm], must not start with '_', '-', or '+'",
 "index_uuid": "_na_",
 "index": "_slm"
},
"status": 400
}

Any idea?

Thanks!

I think snapshot lifecycle management was introduced in Elasticsearch 7.4 so you will need to upgrade to use it.

Just found this knowledge article and it say it is supported from 7.6

Any way to automate snapshots with 7.3? Any workaround?

Thanks!

You can use Curator to create snapshots but it is an external component run from cron and does as far as I know not manage snapshot housekeeping. I would recommend upgrading.

Cheers mate!
