Twice today I’ve had two in complete snapshots, resulting in the overall size of the snapshot (in the main window) being reported as 0 bytes. On both occasions, running the snapshot again seemed to fix it (within a few seconds). I don’t know why it’s failing though and whether it’s something I should be concerned about? For this snapshot I have been incrementally removing ignore rules (to keep some folders from being backed-up straight away - due to the fact that this folder contains a large amount of data). I don’t know whether that is making a difference or not. I also turned on compression after 3 snapshots. I’m just mentioning this in case it’s relevant. Edit: I checked the main.log and there were 4 instances of the following entry (around the timestamp of the incomplete snapshot): > [kopia/content] unable to remove unused index file: remove C:\Users\User\AppData\Local\kopia\f71d2fa0f49cb759\indexes\nd36a2eed6a64393394cde73ed225898b.sndx: Access is denied. ---

None of the changes you’re describing should be causing this behavior. I think this is some weird UI artifact (I’m assuming you are using KopiaUI, is that correct?) ---

BTW. That log entry is also benign. The unused indexes should be removed on next attempt. ---

Yes it’s the UI. Thanks for letting me know. Can I also ask you what the correct syntax is for verifying a specific snapshot? How is each snapshot Identified on the CLI? Do you need to input your username@hostname + source path? ---

On the CLI you can do `kopia snapshot verify --all-sources` ---

This verification may have costs on b2 and aws ! ---

It does have a cost but it won’t download files only metadata (directory listings and manifests) which are typically much smaller.
