I don't know that for sure, but at first glance, i dont understand the complexity of your setup either. Seems to by quite elaborate, which is certainly suiting your needs. And since my base is also quite different from yours, ideas might not transfer that well... but anyhow Here is my use case: Apart from the main system, which resides on an NVME-SSD, all my storage consists of zfs pools, which allow snapshotting (instead of time-shifting). And because of the pools being hosted on raid, there is redundancy PLUS backups (also with partition images among them). Only SOME rarely used data (like movies), i do push into pools on removable media (spinning hard drives), and was interested to have their content searchable online. So i came up with the idea to create a sort of inventory using a sparse copy of empty files only (using mkdir, truncate + touch). The space requirements are affordable (like 2.3M for an inventory representing 3.5T of data). The effect being, that find will see those files by name/directory/time/size and permissions, allowing to find duplicates according to those attributes quite nicely. Since i started doing that, i always do know exactly, what's out there and where to find it, as if i had only the inodes at hand. Suits MY needs. :-) just my 2 cents DdB
