As changes are written to the source files on your agent computer, LiveVault temporarily stores these changes on your computer. These changes are transferred to the backup server according to your backup schedule, where they are written into the associated files.
The minimum requirement for available disk space on the volume or file system to store changes is 15% to 20% free space to allow proper Volume Shadow Copy Service (VSS) function and prevent excessive fragmentation.
During LiveVault agent software installation, the default directory for storing this data is
X: is the drive with the largest amount of free disk space (
/usr/livevault on Linux). You can change this to a different directory with more space available, ensuring that the directory is on a local fixed disk and the volume or file system will not be compressed.
LiveVault monitors and manages disk space on this volume or file system using a variety of methods. If LiveVault determines that disk space is insufficient on the volume or file system for backup operations, it takes the following corrective actions:
It restarts all backup jobs for this agent. This deletes all the unsent caches on the agent, so that LiveVault consumes less disk space on the volume or file system. When the job restarts, LiveVault backs up data about any changes to files.
If disk space is low when a backup job starts, the job fails. LiveVault will retry the job at a later time.
Important: The data on that computer is not protected until the necessary disk space is free on the volume or file system and the changed data has been replicated to the backup server. The time required for the computer to be under protection again depends on the amount of changed data and the speed of your Internet connection.
