About executing file-level backups

Backups can be run immediately or scheduled to run at specified intervals from either the Computer backup subsystem or the Enterprise backup subsystem. Use the Computer backup subsystem if you are new to Unitrends or wish to execute the backup very quickly with little setup configuration for one client at a time. Use the Enterprise backup subsystem to utilize more advanced features, such as option lists, selection lists, and calendars, and to quickly add one or more clients to a schedule. For procedures, see Working with the Computer backup subsystem and Working with the Enterprise backup subsystem.

Protected clients must be online and network communications between the clients and the backup system must be operational for backups to run.

Default exclusions from file-level backups

Maximum file pathname lengths

For some Unitrends agents, there is a maximum file pathname size limitation. File pathnames that exceed this limit are not included in the backup. Agents affected by this restriction and supported maximum file pathname lengths are noted in the following table.
