PeerLock Server is a specialized software tool designed to stop file version conflicts across different company offices and servers in real time. It ensures that when one person opens and changes a file on one server, the exact same file is immediately locked on all other connected servers so no one else can overwrite it.
However, Peer Software (the maker of the tool) has retired PeerLock to focus on a newer, fully combined product called PeerGFS. What Problem Does It Solve?
When teams work from different office locations, companies often copy files across multiple local servers so everyone can open them quickly. The trouble starts when two people edit the exact same file at the exact same time.
The Conflict: Whoever saves last accidentally deletes the other person’s hard work.
The Solution: PeerLock acts like a digital traffic cop. The moment you open a file to edit it, PeerLock freezes that file for everyone else across the entire company network. Other people can only look at the file, but they cannot change it until you close it. Key Features of PeerLock Server
Real-Time Detection: It watches files constantly and spots the exact millisecond a file is opened.
Instant Remote Locking: It locks all other copies of that file across your different business branches instantly.
Cross-Domain Power: It works even if your servers are on completely different network domains.
Works with Microsoft DFSR: It was built specifically to add real-time file locking to Microsoft’s built-in file copying system (DFS Replication), which does not have its own locking system. Current Status: Moved to PeerGFS
Peer Software stopped selling the standalone PeerLock Server. They discovered that trying to lock files with one tool while using a separate tool to copy files caused headaches for network administrators. What is file locking? – Box
