BACKUP FEATURE PROVIDED BY BIDIRECTIONAL SYNCHRONIZED CONTENT MANAGEMENT SYSTEM
The present technology is directed to providing a backup service utilizing a bi-directional synchronization architecture. In order to support both a backup service and a bi-directional synchronization service, the present technology can utilize a special object called an anchor that only permits unidirectional synchronization. Additionally, the present technology separates the backup service from the bi-directional synchronization service. This separation includes utilizing a separate backup directory and bi-directional synchronization directory on a client device, which in turn benefits from the use of a separate instance of the synchronization service on the client device. Further, at the content management system various steps are taken to separate the backup directory from the bi-directional synchronization directory to ensure no objects from the backup directory appear in a user interface related to bi-directional synchronization, and vice versa.
1 . A computer-implemented method for providing a synchronization service and a backup service to a user account by a content management system, the method comprising:
maintaining a user account at the content management system, wherein the user account is associated with a root synchronization namespace, and wherein the user account is associated with a second synchronization namespace represented as a mount under the root synchronization namespace; and
maintaining a backup namespace associated with the user account without mounting the backup namespace under the root synchronization namespace.
2 . The computer-implemented method of claim 1 , wherein the backup namespace is associated with an anchor object type.
3 . The computer-implemented method of claim 2 , comprising:
receiving a request for a graphical user interface for displaying contents of the backup namespace;
retrieving the backup namespace associated with the anchor object type; and
presenting the graphical user interface identifying the backup namespace.
4 . The computer-implemented method of claim 1 , wherein the backup namespace is not associated with a parent namespace.
5 . The computer-implemented method of claim 1 , wherein the backup namespace represents a specific backup location on a particular client device including objects to be backed up by the content management system.
6 . The computer-implemented method of claim 5 , wherein the specific backup location on the particular client device is indicated by an anchor object on the particular client device, the anchor object being maintained as the backup namespace associated with the user account, and being labeled as an anchor object type at the content management system.
7 . The computer-implemented method of claim 5 , comprising:
receiving a change to an object within the backup namespace, wherein a source of the change is from a source other than the specific backup location on the particular client device;
determining that the object is a backup object;
disallowing the change to the object within the backup namespace;
creating a new version of the object; and
storing the new version of the object within the root synchronization namespace for the user account.
8 . The computer-implemented method of claim 5 , comprising:
determining that a user has requested to share an object within the backup namespace; and
disallowing the sharing of the object with the backup namespace.
9 . The computer-implemented method of claim 1 , wherein the root synchronization namespace is monitored by a bidirectional synchronization service and the backup namespace is restricted to uni-directional synchronization.
10 . The computer-implemented method of claim 1 , further comprising:
generating an anchor object for the backup namespace, wherein the anchor object is an object with special attributes;
reading the special attributes of the anchor object;
determining information of a backup directory using the special attributes of the anchor object; and
creating an in-memory map for the backup namespace based on the special attributes to convert between a device unique identifier of the backup namespace to a content management system path in a local tree structure.
11 . The method of claim 10 , wherein the backup namespace is for an external directory.
12 . A non-transitory computer-readable medium including instructions stored thereon, the instructions, when executed by a computing system, being effective to cause the computing system to:
maintain a user account at a content management system, wherein the user account is associated with a root synchronization namespace, and wherein the user account is associated with a second synchronization namespace represented as a mount under the root synchronization namespace; and
maintain a backup namespace associated with the user account without mounting the backup namespace under the root synchronization namespace.
13 . The non-transitory computer-readable medium of claim 12 , wherein the backup namespace is associated with an anchor object type.
14 . The non-transitory computer-readable medium of claim 13 , the instructions being effective to further cause the computing system to:
receive a request for a graphical user interface for displaying contents of the backup namespace;
retrieve the backup namespace associated with the anchor object type; and
present the graphical user interface identifying the backup namespace.
15 . The non-transitory computer-readable medium of claim 12 , wherein the backup namespace is not associated with a parent namespace.
16 . The non-transitory computer-readable medium of claim 12 , wherein the backup namespace represents a specific backup location on a particular client device including objects to be backed up by the content management system.
17 . The non-transitory computer-readable medium of claim 16 , wherein the specific backup location on the particular client device is indicated by an anchor object on the particular client device, the anchor object being maintained as the backup namespace associated with the user account, and being labeled as an anchor object type at the content management system.
18 . The non-transitory computer-readable medium of claim 16 , the instructions being effective to further cause the computing system to:
receive a change to an object within the backup namespace, wherein a source of the change is from a source other than the specific backup location on the particular client device;
determine that the object is a backup object;
disallow the change to the object within the backup namespace;
create a new version of the object; and
store the new version of the object within the root synchronization namespace for the user account.
19 . The non-transitory computer-readable medium of claim 12 , wherein the root synchronization namespace is monitored by a bidirectional synchronization service and the backup namespace is restricted to uni-directional synchronization.
20 . A system for providing a synchronization service and a backup service to a user account by a content management system, comprising:
a memory configured to store instructions; and
at least one processor configured to execute the instructions and cause the at least one processor to:
maintain a user account at the content management system, wherein the user account is associated with a root synchronization namespace, and wherein the user account is associated with a second synchronization namespace represented as a mount under the root synchronization namespace; and
maintain a backup namespace associated with the user account without mounting the backup namespace under the root synchronization namespace.
