Setting Disk Quotas for Windows Users to Avoid Data Loss
A disk quota that applies to a Windows user’s roaming profile folder must be large enough to cover the user’s expected data storage needs for a work session.
A Mac OS X Server PDC enforces quotas on a roaming profile folder only at the end of a work session when the user logs out and the Windows computer copies the local profile to the roaming profile on the server.
If the copied local profile exceeds the quota, the roaming profile won’t be updated with changes affecting the local profile since the user logged in.
If enforcing a user’s disk quota prevents an update of the user’s roaming profile, and the user later logs in using a different Windows computer, Windows could load and apply the outdated roaming user profile from the server.
The server can’t enforce the quota incrementally on the roaming profile folder because the Windows computer updates only the local profile during a work session. (The server enforces a quota incrementally on changes to the home folder.)
A roaming profile folder is subject to the same disk quota as the home directory if both are on the same volume. A user’s profile directory is not subject to a disk quota if it’s on a different volume from the user’s home directory or the home directory is not subject to a disk quota.
Because a quota that covers the roaming profile directory also covers the home directory, make sure the quota is adequate for an entire work session and the user’s home folder. A user’s profile folder includes the My Documents folder and the Internet Explorer cache, which often uses a considerable amount of disk space.
The recommended minimum quotas are:
Â10 MB for a user who logs in only from Windows workstations
Â20 MB for a user who logs in from Windows and Mac OS X computers
Using Presets to Choose Default Home Folders
You can define default home folder settings to use for new users by using a preset to predefine them. For information about defining and using presets, see “Using Presets to Create Accounts” on page 62.
Moving Home Folders
To move a home folder, create a new home folder, copy the contents of the old home folder into the new home folder, and then delete the old home folder.
Deleting Home Folders
When you delete a user account, the associated home folder is not deleted. The administrator must delete the home folder manually by moving it to Trash.
