Overview

Service Overview

File Storage servers connected via network can easily store and share data can, making it suitable for application environments that use multiple servers.
You can select the disk type according to performance requirements, and it will automatically expand or shrink according to the user’s data size without capacity limits.

Features

• Free volume usage: The volume capacity is automatically expanded or reduced according to data creation and deletion without user configuration. There is no cost for creating volumes, and only usage fees for stored data capacity are incurred.
• Various disk types provided: Users can select disk type according to usage purpose. HDD that can store large data cost‑effectively, SSD that provides reduced response time and high IOPS performance, and high‑performance SSD can be used.
• Snapshot Backup: Through the image snapshot feature, recovery of changed or deleted data is possible, and when performing disk backup, snapshots can be stored in a location different from the original. Users select the snapshot created at the point in time they wish to recover from the list and perform the recovery.
• Replication: Creates an identical replica volume at a different location, and the user can set the data replication schedule. In case the original volume cannot be used due to failures or disasters, service can be provided through the replica volume.

• Connection Resources: Virtual Server, Bare Metal Server, Multi-node GPU Cluster can be connected and used.
• Encryption: Regardless of disk type, all volumes are encrypted with the XTS-AES-256 algorithm.
• Snapshot: Through the image snapshot feature, you can create snapshots immediately or schedule them.
  • Retention Count: The number of snapshots retained that are automatically created via schedule
  • Schedule: Snapshot automatic creation interval
  • Recovery: Recover the original volume to the latest snapshot, or select a snapshot at a specific point in time to create a recovery volume
• Replication: Replicates the volume to another location, and the user can set the replication interval.
• Disk Backup: Stores snapshots on backup-dedicated HDD storage and allows you to select the backup location.
• VPC Endpoint connection: File Storage can be used via Private Network connection from an external network.
• Monitoring: You can view usage, IOPS, Throughput, etc., monitoring information through the Cloud Monitoring service.
• ServiceWatch Service Integration Provided: You can monitor data through the ServiceWatch service.

Components

You can create a volume by selecting the disk type and protocol according to the user’s service environment and performance requirements.
When using the snapshot feature, you can restore data to the point in time you want to recover.

Volume

Volume (Volume) is the basic creation unit of the File Storage service and is used as data storage space. Users select a name, disk type, and protocol (CIFS/NFS) to create a volume, then connect it to one or more servers for use.
The volume name creation rules are as follows.

• Must start with a lowercase English letter and can be set to 3~21 characters using lowercase letters, numbers, and special character (_).

Snapshot

Snapshot (Snapshot) is an image backup at a specific point in time. Using the image snapshot feature, you can recover changed or deleted data or store the snapshot in a different location from the original when performing disk backup. The user selects the snapshot created at the point in time they want to recover from the snapshot list and performs the recovery.
The notes for using snapshots are as follows.
