Service Overview

Archive Storage is a storage service suitable for long-term retention of large amounts of data. The user can set a schedule to automatically move infrequently accessed data stored in Object Storage to Archive Storage, enabling efficient storage configuration and cost management. Additionally, upon user request, data stored in Archive Storage can be restored to Object Storage for use.

Features

• Free Capacity Usage: When you create a bucket in Archive Storage, the bucket automatically expands or contracts based on the user’s data archiving and deletion. There is no cost for creating a storage bucket; you are only charged for storage usage.

• Stable Data Recovery: Data that has been stored long-term can be searched and reliably recovered within three hours. During data recovery, select the target file and the Object Storage bucket where you want to store the data to recover it.

• Cost Efficiency: By configuring Object Storage and Archive Storage efficiently according to the purpose and frequency of data usage, you can store and manage data at a reasonable cost.

• Convenient Use: You can conveniently use features such as creating buckets, setting archiving schedules, and data recovery in the Samsung Cloud Platform Console. After migrating data for all files in Object Storage, you can apply a source deletion policy.
