As an update to my previous post on using lambda to automate snaphots, I've finally logged back into the Lightsail console and seen they have added a new feature - automatic snapshots.
There's now an automatic snapshot section - note that the manual snapshots above are the 14 days dutifully maintained by the lambda script
It looks like the feature was added in October, based on the help site.
You're able to change the time the snapshot is taken, but not the amount of history maintained
I won't be switching from the lambda function as I require 14 days on Lightsail boxes, but if you're happy with the following constraints, then it's a great option:
- Pre-set to 7 days of snapshot retention (no more, no less)
- Must be set to run at a specific time (no triggers)
- Available on Linux boxes only (no Windows as yet)
