2. Administrator: users who enter the computer or domain completely and without restriction.
3. BackupOperator: the user used for backup operations.
4. Guest: users with user roles but more restrictions.
5. PowerUser: similar to Administrator but with some restrictions.
6. PrintOperator: Responsible for printer users.
7. Replicator: the user responsible for file copying in a domain.
8. System

NetVault represents another trend in the Linux backup software field. It provides continuous data protection (CDP) through a feature called NetVault: Replicator ). This feature copies byte-level data changes through the LAN or WAN.
Data deduplication is also implemented through Data Domain and other companies in the Linux backup function. These companies provide Data deduplication technology as part of their
APIs and HTTP requests to upload files, modify metadata, and create containers, as well as provide a list of files or containers to the browser. To improve performance, the proxy server can use an optional cache, typically choosing memcache to deploy with a proxy server.
Account Services (Account-server): Manage accounts in the object store.
Container Service (Container-server): Manages the mapping of containers or folders in the object store.

. unfortunately, the maximum length of the optical fiber is limited. The optical fiber system longer than this length must regularly zoom in (copy) the signal. in this case, the signal needs to be converted into an electric pulse, and then restored to an optical pulse, and then transmitted through another line. the device (replicaset) That completes this operation is a weak security link in the optical fiber communication system, because the signal may be intercepted by a wire. there are two way
Service (containerserver): provides container metadata and statistical information (such as the total number of objects and container usage), and maintains the services of the contained Object List. Container service does not know where an object exists. It only knows which objects are stored in the specified container. These object information is stored in the form of SQLite database files and backed up similar to the object in the cluster.
Object Service (objectserver): provides object meta
color gradient that fills the shape of the layer (within the bounds of any rounded corners ). CAEAGLLayer/CAOpenGLLayerUsed to set up the backing store and context needed to dra W using OpenGL ES (iOS) or OpenGL (OS X ). CAReplicatorLayerUsed when you want to make copies of one or more sublayers automatically. the replicator makes the copies for you and uses the properties you specify to alter the appearance or attributes of the copies.

Then, modify the options object and check the number of databases in it.
VaR Options = {port: 5984, method: 'get', path: "/_ all_dbs "};
Will output an array
['_ Replicator', '_ users']
Create a database, which is a put request and the path is the database name.
VaR Options = {port: 5984, method: 'put', path: "/AAA "};
Output OK = true indicates success

Activity)
An activity is the basic unit of a workflow. Each workflow contains several activities and is executed according to certain logic. There are two types of WF: simple activity and compound activity. WF provides a set of standard activity libraries, and you can also customize the activity. All activities are inherited from activity classes. Below is a hierarchy of the most basic activities in WF:
The following is a standard acti
The ruleengine in a workflow is a very important function used to calculate the true and false values of some expressions.
Some other workflows generally use the plug-in ruleengine or implement their own specific engine.
