S3 Backups should use the "Infrequent Access" storage class.

[tabarra]

Currently, all S3 backups are created with the Standard class, but since accessing backups is not done frequently, it should be using one of the Infrequent Access. Compared to the Standard class:

• STANDARD_IA: 45% cheaper
• ONEZONE_IA: 57% cheaper, stored in a single availability zone
• GLACIER_IR: 82% cheaper
  Giving users the option to pick which storage class to use would be great, but setting the default to STANDARD_IA would be a good compromise.

In the long run, the best alternative would probably be to modify the backup system to let S3 manage the lifecycle of the files by creating a lifecycle policy, instead of letting Coolify do it by itself, as that requires the s3:DeleteObject permission, which is deeply flawed as someone that has got access to your coolify instance would also be able to wipe your remote backups.
