bungei running out of space

we got this warning from nagios this weekend:
DISK WARNING - free space: /srv/backups/bacula 1886723 MB (9% inode=99%)indeed, the main storage is full:
Sys. de fichiers Taille Utilisé Dispo Uti% Monté sur
/dev/mapper/vg_bulk-backups--bacula 20T 18T 1,6T 93% /srv/backups/baculaThere's plenty of free space on the VG, however:
VG #PV #LV #SN Attr VSize VFree
vg_bulk 1 2 0 wz--n- 72,60t 51,60tSo this could quickly be resolved by just resizing that partition. But it's interesting to note that the vast majority of storage in use comes from the static content. I suspect there's a lot of duplication around those and we could save space in backups by being a little smarter about this:
