Hi, I am using a backup program called Crashplan to backup my data.
Crashplan relies on spotlight to detect new or modified files. If I create a new file on my boot drive (formatted in APFS), and I run crashplan, it will detect the new file and back it up.
If a create a new file on my ZFS formatted volume, crashplan doesn't seem to detect the new file. I have to run a "verify selection" option in crashplan in order for it detect the file and back it up. During this "verify selection" process, crashplan scans the hard drive to look for any file changes (takes about 2 hours for 2TB).
I confirmed that spotlight is set to index to ZFS volume
There seems to a known issue with spotlight indexes on zfs volume that are deleted at reboot reported at viewtopic.php?f=26&t=2826
Perhaps this is a similar issue with spotlight having problems indexing ZFS volumes?
here's some info on how crashplan and spotlight work

"The CrashPlan app real-time backup feature cannot detect any new or changed files in your file selection if Spotlight does not report the changes to the files to CrashPlan."
