Orbstack is causing bloated Storage
Problem description
When the app Orbstack is installed on the machine, the size of snapshots backing up gets bloated.
Cause
This is due to the Orbstack app which is a containerized solution like Docker and this contributes to bloated size of storage.
The 8 TB data.img file in OrbStack's data is a virtual disk image.
To find the true size of the file, run du -h ~/.orbstack/data/data.img, or look at "size on disk" in Finder's info panel. Sparse files have two sizes: an apparent size (8 TB in this case), and size on disk (actual usage).
Druva captures the apparent size.
Resolution
As a workaround, To exclude containers, images, volumes, and Linux machines from backups, add ~/.orbstack/data to your exclusion list.
