DSM 7.1 Inconsistency between shared folders size and storage analyzer reported disk occupancy

[cgriell]

EDITED : I am a home user (so my knowledge of synology system is shallow) but I am puzzled because the total size of files reported by storage analyzer is 3Tbytes, althoug if I add the size of shared folders in daily reports I get 1.7 Tbytes.

I understand that the operating system, the apps, and in general all the stuff the system needs to run are also stored on disk, but... 1.3 Tbytes?.

BTW, I have deleted recycle bin and scrubbed the drive before posting this.



EDITION: there is a folder called usbshare1 (1.7 Tbytes) that I suppose is the hyperbackup file which should be stored on an external disk. If this is not the case, this should be the reason

...the size of files reported by storage analyzer is 3Tbytes, althoug size of shared folders in daily reports adds up to 2.7 Tbytes only. Somehow 1.3 Tbytes of disk are missing.

? I think your maths / typing is a bit off there...is the difference actually 0.3TB or 1.3TB?

Thanks, FTN, You are absolutely right, my mistake, it's 1.7 Tbytes, (23.9 + 206.6 + 212.5 + 214.3 + 939.4 + 39 = 1,635.7). But... there is a folder named usbshare1, 1.7 Tbytes in size that I assume is the hyperbackup stored on an usb disk

Thanks Telos, I store a relatively stable set of files (copy of my music, photos and videos library), that may grow les than 10 Gbytes per month and Mac Time Machine backups which is now 206.6 Gbytes.

My doubt now is that I have not included in the total amount of 1.7 Tbytes (not 2.7 TBytes as stated in my post) a folder called usbshare1 of 1.7 Tbytes. For me this folder has to be the hyperbackup files stored on an usb external disk, of course, if this is not the case, then this may be the explanation

usbshare is indeed an external USB drive; as @Telos said, the extra space consumed could well be snapshots if its btrfs formatted...

You are probably right! If this is the case, I will open a new thread with my questions derived from that, thanks, Fortran! (I was a Fortran programmer, I loved it, and this gathered my demise to project manager....
