Caching in restic - large retrieve times on some cloud storages

The latency is the trade-off for cheap storage We are taking about a factor of about 5 for storage costs. And the cost depends on the size. So the saving depends on the size and might be some bucks for a small size and even quite some bucks for a bigger size

OVH Cloud Archive charges for incoming and outgoing traffic. Depending on your use case and the amounts of data this can add up really quickly.

In my case I would like to save the money and the trade-off having a 12 hour latency for restoring would be ok. However not ok having a 12 hour latency for backing up…

IMHO OVH Cloud Archive is suitable for a safety copy of a restic repository but not for a primary repository which is accessed frequently. Some of the reasons why such a storage type is not suitable for restic have been discussed in this thread about S3 Glacier Deep Archive.
