HP Enterprise File Services WAN Accelerator manual V3.x on, 104

Control	Description
Mode	Select one of the following options from the drop-down list:
	• Broadcast. The share originates on the origin server and a read-only copy is available
	as a share on the branch-office HP EFS WAN Accelerator. The data is updated
	periodically on the HP EFS WAN Accelerator with the data from the origin server.
	You specify when and how frequently updates (that is, synchronization) are to occur
	when you configure a share.
	IMPORTANT: While performing a incremental synchronization for Broadcast mode
	share, if files are deleted on the server, they are not deleted on the HP EFS WAN
	Accelerator.
	IMPORTANT: For Broadcast mode: if you are performing directory moves regularly
	(for example, mv ./dir1/dir2 ./dir3/dir2), incremental synchronization will not reflect
	these directory changes. You must perform a full synchronization more frequently to
	keep the PFS shares in synchronization with the remote site.
	• Local. After the HP EFS WAN Accelerator receives the initial copy, new data
	generated by clients is periodically synchronized to the origin server. The folder on the
	origin server essentially becomes a back-up folder of the share on the HP EFS WAN
	Accelerator. Users must not directly write to this folder on the origin server. You
	specify when and how frequently updates (that is, synchronization) are to occur when
	you configure a share.
	CAUTION: In Local Mode, the HP EFS WAN Accelerator copy of the data is the
	master copy; do not make changes to the shared files from the origin server while in
	Local mode. Changes are propagated from the remote office hosting the share to the
	origin server.
	NOTE: PFS does not support non-domain accounts other than Administrator accounts.
	If you create Local mode shares on a non-administrator account, your security
	permissions for the share will not be preserved on the origin server.
	• Stand-Alone. Provides the branch-office HP EFS WAN Accelerator with a one time
	working copy of data mapped from the origin server. You can specify a remote path to
	a directory on the origin server, creating a copy at the branch-office. This data is not
	synchronized back to the origin server. The stand-alone share is an initial and one-time
	only synchronization.
Version	Select one of the following software versions from the drop-down list. The controls
	change according to the version you choose. This value represents the version of the
	share that you want to create.
	• Version 2. Specify the server name and remote path for the share folder on the origin
	file server. With v2 you must have the RCU service running on a Windows server—
	this can be the origin file server or a separate server.
	HP recommends you upgrade your v2.x shares to 3.x shares so that you do not have to
	run the RCU on a server. For detailed information, see “Upgrading Shares from V2.x to
	V3.x” on page 107.
	IMPORTANT: If you have shares that were created with v2.x of the HP EFS WAN
	Accelerator software, the account that starts the RCU must have full permissions to the
	folder on the origin file server. Also, the log-in user for the RCU server (which is used
	for v2.x shares) and the share creation user for v3 shares must to be a member of the
	Administrators group, either locally on the file server (the local Administrators group)
	or globally in the domain (the Domain Administrator group).
	• Version 3. Specify the login, password, and remote path used to access the share
	folder on the origin file server. With v3, the RCU runs on the HP EFS WAN
	Accelerator—you do not need to install the RCU service on a Windows server.
	IMPORTANT: Make sure the users are members of the Administrators group on the
	remote share server, either locally on the file server (the local Administrators group) or
	globally in the domain (the Domain Administrator group).
