Consul snapshot compaction

[sgoogal]

consul snapshot size decreased more than 800 MB over the 2 months period even though we did not remove any data from it, is it because of compaction or some other reason, i dont see clear documentation on it in hashicorp.

can someone please throw some light on it.

Hi @sgoogal,

This does not seem like normal normal behavior. Have you tried restoring the snapshot to a test cluster? Does it contain the data you’d expect?

Can you also provide information the version of Consul used on the servers, and the version of the Consul CLI tool that is being used create the snapshot? Thanks.

P.S. - Linking your previous post here as well.

Consul snapshot size reducing daily(from 1GB to 50 MB over the period of one month)

we have our 3 node consul cluster setup for service discovery and also it acts as KV store for vault. our consul backup/snapshot (consul snapshot save backup.snap) size was around 1 GB a month back, now its getting reduced daily few MB’s, and now its 50 MB only. there is not much change in vault KV pairs in this period, we did not delete any data from vault but still we see a drastic reduction size of consul snapshot. any reason for it? if anyone faced this before please let us know.

Hi @blake Thanks for your response.

yes we tried restoring the snapshot and we see the data we expected.

we use consul version 1.2.2 for both servers and CLI
