Abstract
A method of managing data of a file system includes: obtaining information of an unallocated inode that is not currently used because a corresponding file has been deleted based on status of use of inodes stored in an inode bitmap and deletion information of the inodes stored in an inode table; retrieving a backup inode corresponding to the unallocated inode in a journal log area using the obtained information of the unallocated inode; and requesting selection of whether to permanently delete files corresponding to the retrieved backup inode.
Claims14
A method of managing data of a file system performed by a computing system, the method comprising:
- obtaining information of an unallocated inode that is not currently used because a corresponding file has been deleted, based on status of use of inodes stored in an inode bitmap and deletion information of the inodes stored in an inode table;
- retrieving a backup inode corresponding to the unallocated inode in a journal log area, using the obtained information of the unallocated inode;
- and
- requesting selection of whether to permanently delete files corresponding to the retrieved backup inode.
A computing system comprising:
- an application interface configured to request a file list including information of permanent deletion candidate files;
- and
- a file management device configured to obtain information of an unallocated inodes that is not currently used because a corresponding file has been deleted based on status of use of inodes stored in an inode bitmap of a file system and deletion information of the inodes stored in an inode table, retrieve a backup inode corresponding to the unallocated inode in a journal log area using the obtained information of the unallocated inode, and output the information of the permanent deletion candidate files including files corresponding to the retrieved backup inode, in response to the request.
