Consolidation of backups in a cloud depot

Thread needs solution

Situation is as followed:

We have an advanced backup 11.7 running locally and want to use a depot pointing to the cloud.

The question is now how the backup consolidation works?

There's the full backup created through initial seeding and the chain of incremental backups made by the plan.

But how can i free cloud space without breaking the incremental chain? Is there any way to merge incremental backups to a new younger full backup? If so, how's that been done? Where's it been done? In the cloud or do i have to download the complette chain, merge the files and upload it back again to the cloud? Does backup encryption matter in any way?

Hello Michael,

Welcome to Acronis forums! The software uses an "always incremental" archive when the target location is Cloud. Unlike older formats where incremental changes are written into individual files in the backup location, in an always incremental archive type there is physically one file in the archive location while the incremental changes are written to this file directly. This technology helps to avoid complications in retention/deletion of backups specific to the older formats where either a backup with dependencies on it from subsequent backups can be deleted only when all subsequent backups are due to deletion or a space-consuming consolidation process is required.

When a certain backup expires due to the pre-defined retention rules, the backup algorithm just marks these outdated backup blocks as “free” ones. 

Backups can be encrypted using the Advanced Encryption Standard (AES) cryptographic algorithm and the password you set. This guarantees that your data is not accessed by anyone else.

I'd also recommend taking a look at Backup & Recovery FAQ.
