OneDrive for Business file limits
Nathee021 - the limit is currently 300K files syncing. If you have more than that, MSFT warns OneDrive sync client will perpetually be looking at files for status change and therefore perpetual loop. I have one user with 1.5M files, but we only sync about 250K and it works fine (so sync folder selection helps w/ issue).
Hey -thanks for your comment,
I had a couple questions:
1 - is this 300,000 per document library - or - in TOTAL that can be synced?
2- Do you know if that would affect "Files-on-Demand" i.e. A user Syncing 3 or 4 document libraries with over 150,000 in each (total 450,000) but all in "File-On-Demand" so not actually syncing.
Kind regards
I have experimented, and If the Library has over 300k records than it is very slow. So, if you have a single file library with 1 million records, and you try to only sync 250k of those records, it seems OneDrive still loops through all 1 million records at initial sync. This causes huge performance issues.
Lou_Mickley I wonder why they do a "search and destroy" method to find the files that need updating instead of a simple event model, like we use everywhere else?
- #1 - 300K TOTAL across all sources #2 - FonD does not impact this total Issue is not the time to sync the files, the issue is the time it takes to look through all the sources to see if sync of any files needed. As a result, as you get over 300K, you may see perpetual spinning sync icon.
