These are the working folders for the OLB Client.
An explanation of the working folders is given below. Please note that for performance reasons the "Cache" and "Temp" paths should be located on the same drive.
Temp - The temp directory is used as a workspace when the files are patched, compressed and encrypted. The temp folder will be emptied on completion of a successful backup.
Cache - The cache keeps a local, compressed and encrypted, copy of the selected files for a specified number of days. The more days retained in the cache the better the chances are that patches instead of full files are sent during backup. Warning: Specifying a cache retention of "0" will result in patching being disabled. This is not recommended.
Database - The database is used for comparing the latest backup selection with the previous backup to determine the changes.
Note: If the workstation or server does not meet the disk space requirement it is possible to migrate the working folders to another drive. If you choose to migrate these paths to a UNC addressed network share please ensure the client's service permissions are sufficient to access it.
In situations where bandwidth is lacking and disk space is not it may be preferential to process all the data first be sending it to the platform. To do this untick the option "Stream backups directly to the Storage Platform". Please see our Streaming vs Staged KB
Free Hard Disk Space Enforcement.
To ensure that the Backup Client does not use all available hard drive space during data dumps, patching or compression, you can select the "Enforce minimum free space" using the check box, and then specify the amount of free disk space that must remain available.
