bupstash-restore

SYNOPSIS

Efficiently restore the contents of a snapshot into a local directory.

bupstash restore [OPTIONS] --into $PATH QUERY...

DESCRIPTION

bupstash restore performs an efficient set of incremental changes to a directory such that it becomes identical to the requested snapshot. The incremental nature of bupstash restore makes it well suited for cycling between multiple similar snapshots. Note that this operation is dangerous as it deletes extra files already present in the destination directory.

In order to aid file browsing as unprivileged users, bupstash restore does not attempt to restore users, groups and xattrs by default. To set these you must specify the flags --ownership and --xattrs respectively.

The item that is checked out is chosen based on a simple query against the tags specified when saving data with bupstash put.

QUERY LANGUAGE

For full documentation on the query language, see bupstash-query-language.
