I very occasionally backup one of my QNAP drives (with media) to Amazon Glacier. Having not done so for a couple years, I tried to run the backup job, set to only upload changes. The backup failed instantly with Type Date Time Users Source IP Computer name Content
Error 2026/05/27 22:26:19 admin 127.0.0.1 localhost [Hybrid Backup Sync] Failed to complete Backup job: “Cloud Backup 2”. The vault name is not available (already exists). Specify another name.
The job references the vault previously used, as I wanted to do an incremental backup (only changed files). The error message is very confusing. What is going on.please?

We will verify whether this issue exists in the latest available version. However, since your device and software versions are quite old, there may be limitations depending on the model or software version. Thanks!
That error is a limitation of the legacy Amazon Glacier service.
The recommended fix is to switch your target to Amazon S3 with a Glacier storage class instead of the legacy Glacier service. The options map roughly
- S3 Glacier Instant Retrieval – download right away
- S3 Glacier Flexible Retrieval – retrieval in ~5–12 hrs (this is essentially what legacy Glacier was)
- S3 Glacier Deep Archive – retrieval in ~12–48 hrs, lowest cost
You get the same archive-level pricing without the limitation. This is also the direction AWS itself now recommends: What Is Amazon Glacier? - Amazon Glacier
Thanks very much for the info. Not sure I know how to accomplish this. Is this a change I make at the AWS console, or in the HBS3 job set up? Does this mean creating a new target and re-uploading all the backed-up material? If so then how do I release the old vault? If not then can I still do an incremental backup to the old data? Many thanks in advance for your help!
