Doubt about immutability

Post by sarapinho »

Hello people

A question about immutable backups. Today I have this Retention of Backups:

30 points Perfomance Tier
4 Weeks + 12 Months + 5 Years Capacity Tier

In my capacity tier, I will enable the most recent backups after 3 days to be immutable, these 3 days will be immutable, correct?

After these 3 days of backups are immutable, how is this data updated?

Correct.

Not sure whether I follow you on that, we will enable an object lock for the blocks a restore point consists of. The object lock will be set for the duration of immutability + additional period (10 days).

Thanks!

Thanks for the answer.

In addition to the space for the 3 immutables will space be needed for another 10?

For another 7 days on top of your existing 3 days.

Yes, you will need extra space - but not much, since those will be deltas-only... so you'll only need about 20% extra, or even less.

Also, keep in mind that from your total costs perspective, overall this extension actually saves money (by reducing API costs, which can be significant).
