A software tool designed for backing up DVDs.
There are three kinds of backup available in the program: full, incremental, and accumulate. A full backup copies all specified files and leaves no other files on the DVD. In contrast, an incremental backup copies only the files required to make a prior dkop DVD match the disk files exactly. An incremental backup is faster, assuming that most of the files have not changed. Moreover, it removes DVD files that are no longer on the disk, so after an incremental backup, the DVD will exactly match the disk. An accumulate backup, on the other hand, will copy new or changed files to the DVD but won't remove unmatched DVD files.
You can select the files to be copied through the graphical user interface (GUI). You can navigate through the file system and choose files or directories to include or exclude at any level in the directory hierarchy. You can save these selections in a backup job file to automate recurring backups. Once you have included or excluded files or folders from a directory, you should normally only revise the backup job file if you make new exceptions within existing directories or include or exclude new files or directories.
DVD media can be verified in three ways: full, incremental, and thorough. A full verify reads the entire DVD and reports any files with read errors. An incremental verify reads only the files that have been newly recorded by an immediately preceding backup job. While still maintaining a high level of security, this is usually much faster. A thorough verify, on the other hand, reads every file on the DVD and makes a byte-wise comparison with the corresponding disk file. Though not always necessary, it's provided as an extra assurance measure for users.
You can also list all files on dkop DVD media or search for specific files using wildcards. You can compare the DVD with the corresponding backup job file and list all differences, including files that have been created, deleted, or modified since the DVD copy was made. For disaster recovery or file transfer, dkop has a file restore capability, allowing you to select and restore DVD files to their original directories or somewhere else.
Incremental backups update the same media as full backups, making both backup and recovery simple for users. You do not need to track matching sets of full and incremental backup media or restore files from multiple media in the correct sequence. Additionally, command line parameters may be used instead of the GUI interface for use in shell scripts.
Incremental backup and verify may take less than one minute if only a few megabytes of updates need to be added to the DVD media. For larger jobs, the DVD speed determines the time required, and typical values are 200-400 megabytes per minute.
The download tar file includes the source code, a binary executable that might work out of the box, and a complete user guide with some technical information about how dkop works. If the binary doesn't work, you'll need to compile it from the source code. Fortunately, the process is simple and illustrated below.
