Amazon Glacier provides secure and durable data storage at extremely low costs. By backing up files to your Amazon Glacier account, Glacier Backup helps save space on your Synology NAS and provides a contingency plan to avoid data loss.
Before using Glacier Backup, you need to register an Amazon Glacier account. For details regarding Amazon Glacier, please see here.
The Overview page displays information related to the status of backup tasks, such as warnings, scheduled backup time, and the status of restore tasks.
This section explains how to start backing up data stored on your Synology NAS to your Glacier account.
The first time a shared folder is backed up to your Glacier account, a full copy of the shared folder is uploaded. The next time the shared folder is backed up, only modified files are uploaded.
Using remote folders as backup source or restore destination is not supported.
Backup task names can include 1 to 32 Unicode characters and cannot contain the following characters: ! " # $ % & ' ( ) * + , / : ; <= > ? @ [ ] \ ^ ` { } | ~.
Disable this option if you want to remove backed up files at the destination when files are deleted from the source. However, according to the Amazon Glacier pricing policy, you will be charged an early deletion fee by Amazon if you delete backed up files within three months of uploading them. To avoid additional fees, when you disable the Preserve backed up files at destination option, backed up files will be retained at the destination for three months before they are automatically deleted.
Glacier backup tasks can take a long time to complete. You can use this function to cancel backup tasks currently underway.
If you accidentally delete some backup tasks from the Synology NAS, or if you want to download existing backup tasks to a new Synology NAS, you can use this function to download all tasks which are saved to your Glacier account.
Backup tasks will fail if you rename or delete shared folders which are the backup sources of Glacier Backup at Control Panel > Shared Folder.
The default multipart upload part size is 512MB, please set a smaller number if the network environment is unstable.
Files that were previously backed up to your Glacier account can be downloaded and restored to the Synology NAS, allowing you to replace deleted files or download them to a new Synology NAS. This function is only available when a backup task exists on the Synology NAS and the associated files were successfully backed up to your Glacier account. You can choose to restore an archive in the Restore tab, or just a particular file or folder in the Explore tab.
If you want to restore backup files to a new Synology NAS, you can go to Backup and click Retrieve task to download backup tasks which were created on a different Synology NAS. Once the backup tasks are successfully retrieved, you can restore files to the new Synology NAS. See above for more details regarding retrieving tasks.
Restore will fail if you rename or delete shared folders which are the destination of restore at Control Panel > Shared Folder.
