4.52. dump
Updated dump packages that fix three bugs are now available for Red Hat Enterprise Linux 6.
The dump package contains both "dump" and "restore" commands. The "dump" command examines files in a file system, determines which ones need to be backed up, and copies those files to a specified disk, tape, or other storage medium. The "restore" command performs the inverse function of "dump"; it can restore a full backup of a file system. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.
Bug Fixes
- BZ#702593
- Prior to this update, the dump utility passed wrong arguments to the "clone(2)" system call. As a result, dump became unresponsive when executed on the S/390 or IBM System z architecture. This bug has been fixed in this update so that dump now passes correct arguments and no longer hangs.
- BZ#691434
- Under certain circumstances, the dump utility could have failed to detect holes in files correctly. When a user attempted to restore an erroneous backup using the "restore" command, an error message "Missing blocks at end of [path], assuming hole" could have been displayed. In such case, the backup could have not been restored properly. This bug has been fixed in this update so that dump now handles holes in files as expected.
- BZ#658890
- Prior to this update, the "dump -w" command did not recognize ext4 file systems as supported. With this update, the bug has been fixed so that "dump -w" now recognizes the ext4 file systems as supported.
All users of dump should upgrade to these updated packages, which fix these bugs.
