Configure Distributed File System Flashcards
DFS
Distributed File System
Creates a server-agnostic UNC path to a store of data, which can be moved from server to server as needed.
Single, unified namespace to access shared folders hosted across one or more servers.
DFSR
Distributed File System Replication
allows files to be replicated between servers, providing duplicate information in multiple locations. Creates redundancy.
Because DFSR is a ___ directory with links to physical data, the ____ can be moved without having to make changes to how users access the the DFS directory
logical
actual physical data
Compression algorithm used by DFSR
RDC
Remote differential compression
“diff-over-the wire” client/server protocol that can be used to efficiently update files over a limited-bandwidth network. RDC detects insertions, removals, and rearrangements of data in files, enabling DFSR to replicate only the changed file blocks when files are updated.
Benefits of DFS
Unified namespace
Data redundancy - access to data stored on multiple servers
Automated data replication via DFSR
Distributed data consolidation - unified namespace for several distinct datasets
DFS namespace
Unified namespace that presents a centralized view of shared folder data in an organization
DFS namespace server
The server that hosts the DFS namespace, but not necessarily the data
DFS namespace root
The top level of the DFS tree that defines the namespace for DFS. Domain-based root (jenkinslaw.org) adds fault-tolerant capabilities to DFS by allowing several servers to host the same DFS namespace root
DFS folder
Folder that will be presented under the root when a DFS client connects. Allow the system to redirect clients to different systems other than the namespace server hosting the root
Folder target
The share (with actual data) hosted on a windows server. DFS folder name and the share name do not need to be the same.
DFS tree
Hierarchy of the namespace.
Referrals
Configuration setting of a DFS namespace / folder that defines how DFS clients will connect to the namespace server, a folder in the namespac, or a particular folder target server.
DFS is best for
Static data. Things that don’t change often.
Dynamic data that changes often isn’t good because sync errors.
Dynamic data that changes unidirectional would work well.
Two components / roles of DFS
DFS Namespace
DFS Replication
DFS Replication
Replicating files from one file server to another
With DFS, you can choose to replicate _____ without the ____
DFS
replication
That is, you can use DFS without replicating among other servers
standalone versus domain-based namespace
standalone has a server name as a unc
domain based has the domain name.
standalone is ideal if no AD exists
domain based stores namespace in AD
Domain based namespace can have multiple roots, multiple names.
Servers in DFS namespace must be in the same AD ____
forest.
Not necesarily the same domain
That HD format is a requirement for DFS
NTFS
Two database issues relatede to DFS
Database corruption
Dirty database
ABE
Access Based Enumeration
MSFT solution that lets me display files only to users that have been assigned permissions
To get ABE as an option for DFS, you must run DFS in _____
2008 mode
This means that the domain level must be set to 2008 or better.
FSRM
File server resource manager
FSRM lets you
configure notification classify rules manage folder quotas create file management tasks configure file screens create storage reports
FSRM’s classification rules
You can require certain file types to be saved in certain areas.
You can classify files based on location, name, content.
RMS
Right Management Service
Encrypt the file and use a licensing scheme that’s attached to a file. This means the encryption follows the file if it’s moved.
Unlike EFS and Bitlocker, whose protection is lost as soon as the file is moved.
You can set up rules – this file cannot be printed, cannot be attached, etc.
Add-DfsrConnection
Creates a connection between members of a replication group.
Add-DfsrMember
Adds computers to a replication group.
ConvertFrom-DfsrGuid
Translates GUIDs to friendly names within a given replication group.
Export-DfsrClone
Exports the cloned DFS Replication database and volume configuration settings.
Get-DfsrBacklog
Retrieves the list of pending file updates between two DFS Replication partners.
Get-DfsrCloneState
Gets the status of a database cloning operation.
Get-DfsrConnection
Gets a connection between DFS Replication partners.
Get-DfsrConnectionSchedule
Gets a connection schedule between DFS Replication partners.
Get-DfsReplicatedFolder
Gets a replicated folder from a replication group.
Get-DfsReplicationGroup
Retrieves a replication group.
