Storage Node with Deduplication data growth
I have a question re how the storage node retains data. Current backup plans run backups weekly and I chose to retain only 2 backups. All are Windows 7/10 x64 PCs.
Right now the storage node is still chewing through space (3.48TB of 3.82TB used) after each machine has backed up at least once and most have backed up twice. Some of the machines are showing 3 backups with the oldest having a trashcan icon when click on "show backups" in the list of machines backed up to the storage node.
So the storage node is growing and likely to reach its max disk space but I'm not sure if this is because of normal data growth or because the storage node is keeping more than 2 backups in a sort of "recycle bin" and that is eating up data.
Also, how does one get statistics from the storage node of what each machine is using for data? The reported "size" of each machine in the storage location view seems rather small. Is there a web service or anything I can query on the storage node? The SQL DB for the AMS doesn't seem to hold any data about the storage node.
thanks

In the next update (Update 2 coming later this year) we will also add per-archive information to show the original data size which was backed up in each backup - the "Size" column will be replaced with "Original data size" one. Still the effectiveness of deduplication can be checked only from entire location statistics, rather than per-archive one.

Vasily, thanks for the great explanation in both posts. They answered my questions.
I will update my ABA version as I was not on build 7970.
I also looked over the file system on the storage node and saw how each machine ID existed there as a directory name and the size of each dir matched what the web console reported for the size of unique data on each machine. Still, it would be great if there were some way I could programmatically query either the SQL DB or the storage node to get this info you're going to add in update 2.
I used to have a number of great automated reports that emailed myself every day with summary info on various things like this on 11.5 (without storage node or managed vault). It'd be great to do that again. It's tough to maintain the 200+ machines we have scrolling through only the GUI.
Thanks as always for your great help. good job Vasily!

Hi Pete,
Thank you for the feedback. For custom reporting options I'd recommended you to also check the following thread where I discussed scripts to be used to retrieve backup statuses from Acronis Management Server (for example save all activities for past X hours in a text file).
Thank you.
