Reading data from StdIn

Sometimes it can be nice to directly save the output of a program, e.g. mysqldump so that the SQL can later be restored. Rustic supports this mode of operation, just supply - as backup source to the backup command like this:

set -o pipefail
mysqldump [...] | rustic backup -

This creates a new snapshot of the output of mysqldump. You can then use e.g. the fuse mounting option (see below) to mount the repository and read the file.

By default, the file name stdin is used, a different name can be specified with --stdin-filename, e.g. like this:

mysqldump [...] | rustic --stdin-filename production.sql -

The option pipefail is highly recommended so that a non-zero exit code from one of the programs in the pipe (e.g. mysqldump here) makes the whole chain return a non-zero exit code.
