Share Access Restriction 
If you wish to limit share access to particular users and/or groups, you can enter their names in the 
Read-only users
, 
Read-only groups
, 
Write-enabled users
, and 
Write-enabled group
 fields.  
The names must be valid accounts, either on the ioSafe R4 or on the domain controller. 
For instance, if you wish to allow read-only access to all and read/write access only user 
fred
 and 
group 
engr
, you would set the following: 
Default:               Read-only 
Write-enabled users:   fred 
Write-enabled groups:  engr 
If you wish to limit the above access only to hosts 
192.168.2.101
 and 
192.168.2.102
, set the 
following: 
Default:               Read-only 
Hosts allowed access:  192.168.2.101, 192.168.2.102 
Write-enabled users:   fred 
Write-enabled groups:  engr 
If you wish to specify some users and groups for read-only access and some for read/write access, 
and disallow all other users and groups, enter the following: 
Default:               Disabled 
Hosts allowed access:  192.168.2.101, 192.168.2.102 
Read-only users:       mary, joe 
Read-only groups:      marketing, finance 
Write-enabled users:   fred 
Write-enabled groups:  engr 
Note that access control will differ slightly from service to service.   
Share Display Option 
Restricting access to a share will not prevent users from seeing the share in the browse list.  In 
certain instances, this might not be desirable, such as for backup shares that you may want to 
prevent users from seeing.  To hide a share, select the 
Hide this share…
 option.  Users who have 
access to this share must specify the path explicitly.  For example, to access a hidden share, enter 
\\host\share in the Windows Explorer. 
Recycle Bin 
The ioSafe R4 can have a Recycle Bin for each share for Windows users.  You will see the 
Enable 
Recycle Bin
 option at the bottom of the 
Windows [CIFS]
 access tab.   
When enabled, whenever you delete a file, the file gets inserted into the Recy cle Bin folder in the 
Share rather than being permanently deleted.  This allows for a grace period where users can restore 
deleted files.
