In the documentation for snapshot.expiry it just says:
snapshots.expiry
When snapshots are to be deleted
Key: | snapshots.expiry |
---|---|
Type: | string |
Live update: | no |
Specify an expression like 1M 2H 3d 4w 5m 6y
.
But it doesn’t say what the given value would actually do. Does it mean that snapshots older than approximately 6 and a half years will be deleted? (In which case it would be clearer as 6y 5m 4w 3d 2H 1M
, as you would speak it)
Or is it keeping some snapshots for 1 minute, some snapshots for 2 hours, some for 3 days, and so on?
Also, is a “month” a calendar month, or some static value like 30 days? Otherwise, a period like “6 years, 5 months, 4 weeks and 3 days” is variable, depending on the current year and month.
Thanks!
