Dump/Restore

The dump package contains both dump and restore. Dump examines files in a filesystem, 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 filesystem. 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.

  •  02 Jan 2006 19:32

    Release Notes: This is a maintenance release, fixing a few bugs related to the restoration of ACLs and huge backups (symtab over 2GB in size). The directory hash indexing has been made optional since it may require too much memory when restoring huge backups.

      Release Notes: This release features a few bugfixes and support for ext2/ext3 extended attributes (EA).

      •  21 Jan 2005 11:59

        Release Notes: This release fixes a few bugs introduced by the previous version, most importantly a bug in 'restore -C' which could cause damage on the filesystem being compared.

        •  07 Jan 2005 17:16

          Release Notes: This release features several small bugfixes and a number of performance enhancements. The next version of dump/restore will feature EA/ACL support, and there is already a beta patch implementing this. All users of EA/ACLs are welcomed to test this patch and report back.

          •  07 Jul 2004 17:45

            Release Notes: This release fixes a serious bug in dump where a filesystem offset could have been miscalculated on large filesystems, leading to "bread lseek errors". There are some other minor fixes/features.

            QFA with non-tape device (also: an "rmt" that support tape-like CD access?)
            It would be nice to add QFA support for non-tape devices (i.e. for backing up to several CDs). Isn't that pretty easy to do?

            Also, I've been thinking about making a hacked rmt that makes CD writing look like a tape, with support for basic MTIO emulation. That way, any tape-oriented backup can use CD without special code, if it supports remote tapes. OR, use fusd to make a user-space fake tape device for local access. BUT, it looks like dump is already doing OK with CDs, so maybe that's all just too much work.
