How to back up an ASUSTOR NAS to dosya with Cloud Backup Center

Before you start

• A dosya account. Free includes 5 GB, enough to test the setup; pick a paid plan for the full backup.
• Cloud Backup Center installed and updated from App Central (1.0.3 or later on ADM 4, 1.0.4 or later on ADM 5).
• The NAS clock synced with an NTP server in Settings > Regional Options. S3 sign-in fails if the clock is off by more than a few minutes.

Set up the backup

1. 1

   Create S3 credentials in dosya

   In the dosya web app, open Profile > API keys and create a key for the NAS. Limit it to S3 and to the workspace you will back up to, then turn on S3 credentials. Copy the access key ID and secret key now; the secret is shown once. Your workspace ID, which is the bucket name, is on Integrations > S3.

   Using SFTP instead? Limit the key to SFTP, and skip to the SFTP step below.

2. 2

   Start a new S3 job

   Open Cloud Backup Center, click Start (or the + button), choose Amazon S3 as the service and click Next. Then fill in the connection like this.

3. 3

   Pick folders and the bucket

   Select the NAS folders to back up and tick 1-on-1 Folder Synchronization so later runs send only changes. As the destination, pick your workspace ID from the bucket list and a folder inside it.

   Pick the existing bucket. dosya buckets are workspaces, so New Bucket is refused.

4. 4

   Schedule it

   Choose Scheduled backup and set a time, nightly for most people. In the advanced settings, name the job, tick Enable multipart uploads and set Maximum simultaneous transfer to 4 or fewer. Add a Bandwidth limitation if you need one, then click Finish.

5. 5

   Or connect over SFTP

   If you prefer SFTP, start a new job, choose SFTP as the service and enter these details. Then pick folders and a schedule as above.

   Host

   sftp.dosya.dev

   Port

   2222

   Username

   Your dosya account email

   Password

   An API key (dos_…) limited to SFTP

6. 6

   Run it and test a restore

   Run the job once with Back up now. When it finishes, restore one folder to a new location (next section) and open a few files, so you know the backup works before you need it.

Restore files

1. 1

   Restore with a download job

   In Cloud Backup Center, create a new job with the same dosya connection and set Transfer mode to Download. Choose the backup folder in dosya as the source and an empty NAS folder as the destination, then run it once.

2. 2

   Restore a single file or an older version

   Sign in to the dosya web app, open the workspace and download the file. For an earlier version or a deleted file, use the file's version history or Trash.

Restore to a new NAS

1. 1

   Install Cloud Backup Center on the new NAS

   Set up ADM, sync the clock and install Cloud Backup Center from App Central.

2. 2

   Download everything back

   Create a Download job with the same S3 or SFTP details (a new dosya key works) and run it into an empty folder. Downloads are free on paid plans.

3. 3

   Start backing up again

   Create the upload job again, pointing at the same dosya folder. With 1-on-1 Folder Synchronization, files that are already there and unchanged are not uploaded again.
