Hello!
On 5.6.1-SP2 AEM productive instances, I made data-packages to export them (with a total of a few tens of GB). After building the packages (on the author), the instance size increased on the disk.
Once the packages downloaded, I deleted them from the package manager. The reported instance size returned at its original size (before packages building), but the disk usage never decreased, and this that's a lot problematic...
The packages are probably kept by the versioning tool of AEM, even if they do not exist anymore in the package manager. But how to do to purge them ?
A very big thanks for your help, and merry Christmas and happy New Year to all of you!
