Structure of an inSync storage
inSync supports the creation of two types of storage: file store and object store.
- A file store uses a data store for storing data that inSync backs up from user devices. In a data store, deduplicated data is stored in data volumes.
- An object store uses a swift store for storing data that inSync backs up from user devices. In an object store, deduplicated data is stored as objects within the OpenStack Swift object store deployed in the organization's data center.
- Both file store and object store contain a database folder and database log folder. The database folder contains metadata information that inSync uses for data deduplication. The database log folder contains logs for all transactions that occur in the database folder.
This document is for general guidance on the types of storage that are supported. However, inSync Storage with Object Store deployment varies based on API compatibility and other factors. To know whether your environment qualifies for Object Store deployment, contact Druva Support.
The following diagram explains the structure of both types of storage.
Difference between file store and object store
The following table lists the difference between file store and object store.
|Property||File Store||Object Store|
|Deduplicated data stored in...||File system||
Note: inSync supports object store implemented with OpenStack Swift in conjunction with OpenStack Keystone only.
|Increase storage capacity by...||Adding up to 10 data volumes.||
Increasing the size of the storage.
Note: Before you increase the size of your object store, ensure that your hardware can support the updated size of your object store.
|Maximum size||64 TB||
Note: A single implementation of Swift can contain multiple inSync storage.
|Support for storage pools||Yes||No|
Guidelines for creating a storage
The following table lists the guidelines for creating a storage.
|Data folder (for a file storage)||
Note: For a backup to be successful, there must be at least 10 GB of free space on the storage data folder. inSync checks for this condition every 10 minutes and if it is not satisfied, ongoing backups are stopped and scheduled backups are put on hold. Backups do not start until you increase the free space to at least 50 GB.
|Database log folder||
