[Question] Why is snapshot_hash used instead of snapshot ID? about restic-exporter

[ngosang]

For each snapshot restic provides several hashes:

"parent":"caf9137c9bccc0d2b266a0fc02be7a71652f3de4916034a234e535a3e9ef3a11",
"tree":"446e26b7a79b7b08f52d2e183cbbc9be948e0e56787a69aae3c2f9e63fbbd07c",
"id":"100c00902e666e25570773885e82200a982c4334268f1d608f138384de629915",
"short_id":"100c0090"

But none of them is useful to group all snapshots for the same user. In the first implementation I though that the "parent hash" was common across all snapshots of the user but it's not.
I decided to make my own hash which means nothing but it's useful to group snapshots of the same user.
I'm not publishing the restic hashes because they are not useful and they will generate too many time series in Prometheus.

Ok, that makes sense. Thanks!

I suppose that I will investigate on why my client appears duplicated, and I will open a new issue or PR if there is any enhancement :-)

As explained in #16, in my case I get duplicates because of path changes (I added a couple of directories for a given host and user).
