How can I get cdbkup to archive more than one filesystem?
This is a common request since many people have /home and /usr on separate partitions from the root partition, or other similar setups. By default, cdbkup skips over directories that reside on other filesystems. The –cross-mp (-m) option tells cdbkup to include these mount points as though they were plain subdirectories. See cdbkup (1) for more details. How do I restore individual files from a backup? This is easy to do, but not very efficient, since the archives are in tar format, and usually compressed. To restore /etc/file1 and /root/file2 into the directory /tmp/restore, use the following: mkdir -p /tmp/restore cd /tmp/restore cdcat | tar xvfz – ./etc/file1 ./root/file2 This assumes that gzip compression was used. Otherwise, change the tar options to xvfj (for bzip2 compression) or xvf (for no compression). How does cdbkup keep track of dump levels cdbkup uses GNU tar’s incremental backup facility in order to implement backup levels. It does this by storing .snar files for each ba
