Back up a QNAP NAS with HBS 3

Hybrid Backup Sync 3 talks to any S3-compatible server through its S3 Compatible storage space. Point it at CloudBox Vault and your QNAP keeps an encrypted, versioned off-site copy in the UK.

Applies to: QTS 4.4 / QTS 5 and QuTS hero with HBS 3. Labels may differ slightly between versions.

1 · Create a key and a bucket

In your CloudBox dashboard → Backup: Create access key (copy the secret now) and Create bucket. Leave Object Lock off — HBS 3's versioning deletes old versions, which Object Lock would block.

Setting	Value
Endpoint / server address	`https://s3.cloudbox.biz` (some tools want just `s3.cloudbox.biz`)
Region	`uk-1` — if the tool has no region field, leave it; the gateway accepts the default
Signature	Version 4 (V4)
Addressing	Path-style (`s3.cloudbox.biz/bucket/key`). Bucket-in-hostname addressing is not available yet.
Access key ID	`CBX…` from the Backup tab → Create access key
Secret access key	shown once when the key is created
Bucket	created in the Backup tab; lowercase letters, digits and hyphens, no dots
TLS	Yes — a normal public certificate, so leave certificate validation on

2 · Add CloudBox as a storage space

Open HBS 3 → Storage Spaces → Create.
Choose S3 Compatible.
Fill in: Name CloudBox Vault · Server address https://s3.cloudbox.biz · Signature Version 4 · Access key / Secret key from the dashboard. Keep the secure connection (SSL/TLS) and certificate validation on — the certificate is a normal public one.
Click Test; it should succeed. Create.

NoteHBS 3 uses path-style addressing (s3.cloudbox.biz/bucket), which is what Vault supports today.

3 · Create the backup job

Backup & Restore → Create → New backup job.
Select the folders to back up.
Destination: the CloudBox Vault space → your bucket → a folder for this NAS.
Methods / options: enable client-side encryption and set a strong password (keep it off the NAS); QuDedup saves space but stores .qdff files that need QNAP's QuDedup Extract Tool to restore elsewhere; set versioning (a version count) and a schedule.

4 · Run it and check

Run the job. When it completes, the CloudBox Backup tab shows the bucket's usage within the hour. Do one test restore (Backup & Restore → Create → Restore job).

TipRestores and HBS 3 integrity checks read data back and count toward the monthly download allowance (3x what you store).

If something does not work

Test fails: the server address needs the https:// prefix, Signature Version must be 4, and the NAS clock must be right (Control Panel → General Settings → Time).
QuotaExceeded during backup: the plan is full — reduce versions, or move up a plan.

Questions

Which HBS 3 storage space type do I choose?

S3 Compatible (in the cloud storage list). Server address https://s3.cloudbox.biz, Signature Version 4, your access key and secret, secure connection on with certificate validation on.

Should I use QuDedup?

It saves space and bandwidth, and it changes the format: backups are stored as .qdff and restoring elsewhere needs QNAP's free QuDedup Extract Tool. Fine if you know that; leave it off if you want plain files.

Should I enable client-side encryption?

Yes. HBS 3 encrypts before upload with a password you set. Keep it somewhere other than the NAS: without it the backup cannot be restored by anyone, including CloudBox.

Can I use Object Lock with HBS 3?

No. HBS 3 versioning rotates old versions by deleting them, which Object Lock would block. Leave Object Lock off for HBS 3 buckets.
