To change the location of the working folder:
Open the ESE Agent and go to Tools > Options > Advanced. Under Working Folder, click Change and select a new location.
To configure the cache:
Open the ESE Agent and go to Tools > Options > Advanced. Under Working Folder, select one of the options for Cache Indexes and click OK.
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.
