snapshots command shows all snapshots that belong to a specific repository.
To find a list of available repositories to query, the command
/_cat/repositories can be used.
Querying the snapshots of a repository named
repo1 then looks as follows.
Which looks like:
id status start_epoch start_time end_epoch end_time duration indices successful_shards failed_shards total_shards snap1 FAILED 1445616705 18:11:45 1445616978 18:16:18 4.6m 1 4 1 5 snap2 SUCCESS 1445634298 23:04:58 1445634672 23:11:12 6.2m 2 10 0 10
Each snapshot contains information about when it was started and stopped.
Start and stop timestamps are available in two formats.
HH:MM:SS output is simply for quick human consumption.
The epoch time retains more information, including date, and is machine sortable if the snapshot process spans days.
