[0041] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the following further elaborates on the embodiments of the present invention in detail with reference to specific embodiments and the accompanying drawings.

[0042] It should be noted that all the expressions using "first" and "second" in the embodiments of the present invention are used to distinguish two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units inherently includes other steps or units.

[0043] Based on the above objectives, in the first aspect of the embodiments of the present invention, an embodiment of a file archiving method is proposed. Figure 1 The following shows a schematic diagram of an embodiment of the file archiving method provided by the present invention. As Figure 1 shown, the embodiments of the present invention include the following steps:

[0044] Step S10: Configure a special archiving user in Samba, and set an ACE corresponding to the special archiving user on the client side, which records the storage medium level;

[0045] Step S20: In response to Samba receiving an access request for a file and the corresponding ACE, check whether the user corresponding to the access request is a special archiving user;

[0046] Step S30: In response to the user corresponding to the access request being a special archiving user, check the ACL in Samba to confirm whether there is an ACE of the special archiving user therein;

[0047] Step S40: In response to the non-existence of the ACE of the special archiving user in the ACL, write the ACE corresponding to the access request into the ACL as the specific ACE of the special archiving user;

[0048] Step S50: Parse the specific ACE to obtain the storage medium level recorded therein, and write the recorded storage medium level into the extended attribute of the file, so as to migrate the file to the corresponding storage medium for archiving according to the storage medium level in the extended attribute of the file.

[0049] Samba is a software that implements the SMB protocol on Linux and UNIX systems and consists of a server and client programs. SMB (Server Messages Block) is a communication protocol for sharing files and printers on a local area network, which provides shared services for resources such as files and printers among different computers within the local area network. The SMB protocol is a client / server type protocol, through which a client can access shared file systems, printers and other resources on a server.

[0050] ACL (Access Control List) is an access control technology based on packet filtering. It can filter data packets on an interface according to set conditions, allowing them to pass or discarding them. Access control lists are widely applied to routers and layer-3 switches. With the help of access control lists, the access of users to the network can be effectively controlled, thus ensuring network security to the greatest extent. ACE is an access control entry in the ACL.

[0051] In the embodiment of the present invention, by setting a corresponding ACE recording the storage medium level for the special archiving user, it is distinguished from other ACEs in the ACL; by checking whether the user corresponding to the access request for the file is a special archiving user, and when the user corresponding to the access request is a special archiving user and there is no ACE of the special archiving user in the ACL in Samba, writing the ACE corresponding to the access request into the ACL and parsing the ACE, thereby obtaining the storage medium level recorded therein; by writing the recorded storage medium level into the extended attribute of the file and migrating the file to the corresponding storage medium for archiving according to the storage medium level in the extended attribute, the storage and archiving of files according to the storage level are flexibly realized.

[0052] In some embodiments, checking the ACL in Samba to confirm the existence of the ACE of the special archival user therein includes: checking the operation permissions on the file recorded in the ACL to confirm the existence of the ACE of the special archival user therein.

[0053] In some embodiments, checking the operation permissions on the file recorded in the ACL to confirm the existence of the ACE of the special archival user therein includes: checking whether the ACL records the permissions for restricted read and write operations on the file; in response to the ACL recording the permissions for restricted read and write operations on the file, confirming the existence of the ACE of the special archival user in the ACL based on the permissions for restricted read and write operations.

[0054] In the above embodiments, for the ACE of the special archival user, it does not have the permissions for read and write operations on the file because it is mainly used to assist in storing the file to the corresponding level of storage medium; while the remaining ACEs in the ACL have the permissions for read and write operations on the file.

[0055] In some embodiments, the method further includes: in response to the existence of the ACE of the special archival user in the ACL, merging the ACE corresponding to the access request with the existing ACE.

[0056] In this embodiment, if the ACE of the special archival user already exists in the ACL, the ACE corresponding to the access request is merged with the existing ACE. Specifically, the permissions of the two are merged, that is, only one copy of the same permissions is retained, and the permissions that the ACE corresponding to the access request has more than the existing ACE are also retained.

[0057] In some embodiments, setting the ACE corresponding to the special archival user and recording the storage medium level at the client includes: setting the ACE corresponding to the special archival user at the client, where the ACE includes multiple entries, and several of the multiple entries record the storage medium level correspondingly.

[0058] In this embodiment, the client mainly includes but is not limited to a CIFS client. A CIFS client is a client that uses the CIFS protocol. The CIFS (Common Internet File System) protocol is a file sharing protocol, which is developed by Microsoft on the basis of SMB and extended to the Internet protocol. The CIFS protocol has three versions: SMB, SMB2, and SMB3. Now SMB2 and SMB3 are more commonly used. It enables programs to access files on remote Internet computers and requests services from this computer. CIFS uses the client / server mode. The client program requests services provided by the server program on the server. The server obtains the request and returns a response.

[0059] The CIFS client runs on the Windows system, and users cannot make any modifications to the client. The present invention utilizes the file system semantics of CIFS to be compatible with the original Windows applications. By setting a specific user as the archival user and setting the access control entry (ACE) of the user for files / directories, and by modifying the Samba process to parse the ACE and convert it into hierarchical storage semantics, the underlying file system or data migration process performs hierarchical archival storage according to the semantics. Based on security, the archival user has no permission to access shared files (i.e., no read / write operation permissions for shared files). ACE is a 32-bit unsigned integer string, and examples of partial conversion semantics are shown in the following table:

[0060] Table 1 Partial Conversion Semantics Table of ACE

[0061]

[0062]

[0063] In the above table, for the ACE, the semantics corresponding to the read-related permissions (such as READ_ACL, READ_ATTRIBUTES, READ_NAMED_ATTRS) are preferentially selected and set as the storage levels (such as primary storage, secondary storage, tertiary storage). The "reserved" semantics therein indicates retaining the original semantics of the ACE. Three storage levels are set in the above table. If there are multiple storage levels set, the highest storage level (such as primary storage) is selected as the selected storage level.

[0064] In some embodiments, configuring a special archival user in Samba includes: selecting an existing user in the active directory of Samba as the special archival user, or creating a new special archival user in the active directory of Samba.

[0065] In this embodiment, configuring a special archival user in Samba can change an existing user in the active directory of Samba to a special archival user, or a new special archival user can be selected.

[0066] In some embodiments, writing the recorded storage medium level into the extended attributes of a file to migrate the file to the corresponding storage medium for archival according to the storage medium level in the extended attributes of the file includes: writing the recorded storage medium level into the extended attributes of the file and sending a notification of successful writing to the file system; in response to the file system receiving the notification, migrating the file to the corresponding storage medium for archival according to the storage medium level in the extended attributes of the file.
