This question is motivated from a reply by Craig Sanders. Thanks, Craig!
In what case, are byte or block level backups, i.e. disk or partition image backups, more suitable than file-based backups?
For example,
for routine backup of partitions and disks,
for case of emergency when data is lost, and one would like to create a copy and restore later, in order to perform different data recovery applications/methods to see which one actually works.
One example of byte or block level backups, i.e. disk or partition image backups is dd
.
Some examples of file-based backups are cp
and rsync
.
Thanks!
