Remote data replication overview Remote data replication Data replication, also known as remote folder mirroring or folder synchronization, occurs when the same folder contents is duplicated across 2 or more computers, often across wide area networks (WANs) or geographically dispersed offices Must support large data sets: – Complex directory tree structures – Thousands or even millions of files – Combination of small and very large files up-to terabyte Wide Area Files System, ideally must work at file system level to prevent continuous scanning of folders. | © Copyright FileCatalyst,

Remote data replication scenarios Remote data replication is often used when organizations require consistent data across multiple geographical locations. Possible use cases: – Remote Backups for disaster recovery – Mirroring of Data across multiple offices (for faster data access) – Moving the data to the edge (closer to the consumers) – Global Content Distribution Network (CDN) | © Copyright FileCatalyst,

Data replication vs. sync Replication (or mirroring) involves a single master node and one or multiple slave nodes Sync involves multiple nodes all acting as master nodes. Every node can modify any file in the folder. – Sync requires complex rules to prevent and handle collisions – Sync across more then 2 master nodes is even more challenging – Sync is not recommended with FileCatalyst HotFolder | © Copyright FileCatalyst,

Replication tools within FileCatalyst (Cont’d) Hotfolder features useful for data replication: Scheduler for tasks and bandwidth File System Events Delta (RSYNC) Data-set rules Monitoring and notifications ZIP chunking MD5 File transfer cache | © Copyright FileCatalyst,

Platform specific gotchas Common file attributes for all platforms: File name, Date Created, Date Modified, Owner | © Copyright FileCatalyst, Operating SystemFile Attributes MacOSExtended attributes (xattr), Resource Forks, Symlinks, Permissions (Read Write Execute), Access Control Levels (ACL’s) WindowsPermissions, Attributes: Read Only – Archive - Hidden – System, Security Attributes LinuxPermissions (group, user, other)

Data replication across operating systems Extended File Attributes are LOST when moving a file between operating systems. But it’s OK because extended attributes may not be always needed. | © Copyright FileCatalyst,

File system events The file system events provides a way for an application to ask for notification when the contents of a directory hierarchy are modified. For example, an application can use this to quickly detect when the user modifies a file within a folder using another application. Avoid scanning large folders to detect changes! Use file system events File system events only work on local drives (no SMB or other network drive technology) Transfer the initial file set without file system events, THEN turn it on. | © Copyright FileCatalyst,

HotFolder to HotFolder replication 2 Hotfolders connected to the same FileCatalyst Server Replication can be done between both HotFolders All the data will go through the server, however no data will be stored on the server This reduces the amount of disk space required at the server | © Copyright FileCatalyst,
