Cloud storage

Cloud storage is offered in a variety of technologies and implemented in different ways. There are basically three types: file storage, object storage, and archival storage.

File storage is similar to regular file system in your computer, so you can manage your data in the cloud storage in a similar way. File-based cloud storage services tend to offer features not only data storage but also applications, like online editing and collaboration. Most of them are marketed as drives, like Google Drive, Amazon Drive, or Microsoft One Drive, and they tend to support only proprietary APIs. WebDAV is the most popular protocol supported by file-based cloud storage.

Object storage is designed for massive scalability and high availability. Every object is independent from other objects and there is no tree-like folder structure. You may think of objects as a huge number of files in single folder and there is no subfolder. Each object is identified using a key (a text string as a unique identifier), and people tend to use path-like keys to manage objects. For example, you may have two objects “/abc/object1” and “/abc/object2”, such that object storage client applications can present the two objects, “object1” and “object2” as two files in a folder, “/abc/”. In fact, there is nothing named as “/abc/” in the object storage.

Archival storage is an emerging cloud storage service. It is similar to object storage, but it is designed for storing infrequently accessed (cold) data and for lower costs, so it takes longer to retrieve an archived object, together with some extra limitations.

To overcome the varieties in cloud storage technologies and to provide consistent user experiences, Cloud Backup Sync App transforms your files and folders into various cloud storage technologies and manage your data in the cloud storage in a way that takes the most features of the cloud storage technologies.

Cloud Backup Sync App allows you to configure multiple accounts and storage spaces, each of which represents the cloud storage service and the credentials needed to access the cloud storage. When you create a backup and restore job, you can specify the storage space to be used for the job, instead of entering the account information for each job. You can change the account and storage space information in one place to make it effective for all related jobs. This simplifies your configuration process.

To learn more about the characteristics of each cloud storage service and how to create an account and storage space, please check the following information:

  • Amazon S3
  • Amazon Glacier
  • Azure Storage
  • Google Cloud Storage
  • OpenStack Swift
  • WebDAV

In most cases, you will need to have only one account for every job. However, you can use multiple accounts for better security and for separating accounts. If you want to store your data to different locations for risk mitigation or cost reduction, you can also have one account for each location. As the rate limit control is on a per-account basis, you can have different rate limit settings for the same cloud storage by applying different accounts for jobs.

Cloud Backup Sync also allows you to create a sync job to cloud storage. It supports OneDrive, Dropbox, Amazon Drive, Google Drive, Box, and Yandex.disk.

However, as cloud storage technologies quickly evolve the information provided here is only for your reference and may be outdated. Please consult your cloud storage vendor for detailed information.

Introduction

Overview

QNAP offers an easy-to-use, feature-rich, and secure cloud backup sync solution that protects your data by storing a copy of it in cloud storage, archives aged data to the cloud storage for long-term preservation and syncs data between local NAS and multiple cloud services. A variety of enterprise-class public cloud storage services are offered, including Microsoft Azure, Amazon S3, Amazon Glacier, Google Cloud Storage, Rackspace, IBM SoftLayer, and more. You can also use private cloud storage solutions that are compatible with S3, OpenStack Swift, and WebDAV. In addition, you can sync your data to Amazon Drive, OneDrive, Google Drive, Dropbox, Box and Yandex.disk.

Miscellaneous

Transfer rate control

The Cloud Backup Sync App allows you to configure data transfer limits for each account. The maximum rate for uploading and downloading can be configured separately. You can also configure the time interval and the days of the week to apply the limits. For example, enable it only during office hours on working days to avoid saturating your Internet bandwidth and reducing the performance impact on regular Internet usage. It also helps to reduce the cost of your cloud services if you are offered a free quota of data access within a period of time.

Reporting issues

The Cloud Backup Sync App internally generates debug logs for facilitating troubleshooting. Please click on the “Help” button on the top-right corner of the App’s window. Click “Download Diagnostic Report” to download the debug log file for sending it to the QNAP Helpdesk with your problem details.

Sync

Creating a sync job

The Cloud Backup Sync App allows you to create a sync job to sync data between local NAS and multiple cloud storage like Google Drive, Dropbox, Amazon Drive, OneDrive, Yandex.disk and Box. It also provides one-way (upload and download) and two-way synchronization.

The Cloud Backup Sync App helps you to create a sync job with the following steps:

  1. Click the “Sync” icon in the overview page to create a cloud sync job.
  2. Select one-way or two-way sync and click “Sync with the cloud”. If you select one-way sync, you also can choose upload or download.
  3. Select an existing cloud account or click the cloud service icon to create a new account to create the sync job.

Using Dropbox as an example, the Cloud Backup Sync App will open a new page to let you authenticate with Dropbox. Enter the login credentials of your Dropbox account and click “Sign in”.

Note: The sign-in window is controlled by cloud vendor. Different cloud services have different log in screens.

After entering the required entries and closing the dialog box, the account information will be tested. The testing includes (but is not limited to) the following items:

  • Validate Server URL
  • Validate account credentials
  • Validate the account has enough access rights to carry out the actions required by sync jobs.

If authenticated successfully, your account will show at the above list. Then you can select this account and click “Next” to create a job.

  1. Select a cloud account and click “Next” to create a sync job. Enter the job name, source folder, destination folder, set schedule and other advanced settings to finish creating a sync job.
  • Schedule
    Sync job provides five types of schedule like start manually, continuous, periodically, run once and after this job finishes. Every setting is same with backup jobs.
  • Advanced Settings > Policy
    Configure the following job policies:
    (1) Client side encryption: You should first go to “Storage Space > Profile” and edit your cloud account to set client side encryption. Read the messages carefully before entering the encryption password, check “I understand” and click “OK” to finish this setting. Then, you can enable client-side encryption for a sync job, and the job will encrypt files before uploading them and decrypt the files after downloading them.
    (2) File compression: this setting is same with backup jobs.
    (3) Actions: The App provides three types of action (mirror, copy, and move) to let you choose how to sync your data to the cloud.
    Mirror means your data at local and cloud are identical after synchronization, and extra files/folders at the destination will be deleted.
    Copy will transfer all of the files from the source to destination. Enable “Only transfer updated files” to skip unmodified files. This setting also provides the “Rename/Replace/Skip” conflict policy. Before synchronization, if there are local and cloud files with the same name, Cloud Backup Sync will follow your conflict policy to handle these files.
    Move will delete the files at source after synchronization. You can also set conflict policy as rename/replace/skip. Continuous jobs do not support this action.
    If you create a two-way sync job, you only need to select the conflict policy.
  • Advanced Settings > Filter
    The Cloud Backup Sync App provides various filtering options to help you only sync important data to speed up the sync job, reduce bandwidth usage, and save your cloud expenses.
  • Advanced Settings > Options
    These settings are the same with backup jobs. For “Maximum skipped files”, if you created a continuous job and skipped files are over this number, the job will change its status to “Warning”. If you created a scheduled job, this job will be stopped when skipped files exceed this number.

Editing a sync job

Change the settings of a sync job by clicking the “Edit” icon in the “All Jobs > Cloud Jobs” list. However, the changes will only be applied after the job is executed again.

Viewing a sync job

Examine detailed status and logs of a sync job by clicking the sync job name in the “All Jobs > Cloud Jobs” list. Similar to backup jobs, you can see a sync job’s status, events, transferred files, and history.

Create Sync Job

1. Click “Sync Job Management” > “Create Job”.

2. Click “Next”.

3. Select “Local location”, “Account name”, and “Remote location”, then click “Next”.

4. You can set “Start manually”, “Continuous”, “Periodically”, “Start once at”, and “After this job finishes” as a schedule.

5. Set the file conflict policy then click “Next”.

6. Set filters for file size, file date, hidden files/folders, and file types then click “Next”.

7. Set other options like “Timeout”, “Number of retries”, “Retry interval”, “Maximum skipped files”, and “Concurrent processing files”, then click “Next”.

8. Confirm these settings are correct before clicking “Next”.

9. Click “Finish”.
