raidsm 0 · ID: 1 Posted October 26, 2019 (edited) Hi all! Can somebody help reducing/compacting a DSM VMDK file from 30G to what it's really using (1TB) ? Should I've made a snapshot right after my DSM installed with my packages? I want to make a full backup of my virtual xpenology guest VMware fusion machine (OSX host on a SSD). The thing is the xpenology is using approximately 1 gig MAX but , my VMDK size is about 30 GIG as of now... I must have use this space from previous downloaded files but deleted those afterward. My recycle bin in DSM is turned off and empty. The backup is mainly because I use this for many thing including a docker homebridge setup and some other things and I don't want to start over if my HD dies.. I've read that 1-BTRFS (and EXT4) partition doesn't need to be "defragmented" like a ntfs partition for windows guest vm it seems. 2- can't install VMware tools on DSM guest os 3- As I use a SSD I'm not convince about using a software that zero out all unused bites (unnecessary wear?) thanks for your help! EDIT: I've run the DSM volume defragmentation and no change on the VMDK file size. Volume is at 1.02 GB but VMDK file size still at 30Gb..
