Generally S3 cannot offer the same performance or semantics as a local file system. More specifically:
random writes or appends to files require rewriting the entire object, optimized with multi-part upload copy
metadata operations such as listing directories have poor performance due to network latency
non-AWS providers may have eventual consistency so reads can temporarily yield stale data (AWS offers read-after-write consistency since Dec 2020)
no atomic renames of files or directories
no coordination between multiple clients mounting the same bucket
no hard links
inotify detects only local modifications, not external ones by other clients or tools
