bup-get(1) General Commands Manual bup-get(1) NAME bup-get - copy repository items (CAUTION: EXPERIMENTAL) SYNOPSIS bup get [-s source-path] [-r host:path] OPTIONS <(METHOD ref [dest])>... DESCRIPTION bup get copies the indicated refs from the source repository to the destination repository (respecting --bup-dir and BUP_DIR), according to the specified METHOD, which may be one of --ff, --ff:, --append, --ap- pend:, --pick, --pick:, --force-pick, --force-pick:, --new-tag, --new-tag:, --replace, --replace:, or --unnamed. See the EXAMPLES be- low for a quick introduction. The ref is the source repository reference of the object to be fetched, and the dest is the optional destination reference. A dest may only be specified for a METHOD whose name ends in a colon. For example: bup get -s /source/repo --ff foo bup get -s /source/repo --ff: foo/latest bar bup get -s /source/repo --pick: foo/2010-10-10-101010 .tag/bar As a special case, if ref names the "latest" save symlink, then bup will act exactly as if the save that "latest" points to had been speci- fied, rather than the "latest" symlink itself, so bup get foo/latest will actually be interpreted as something like bup get foo/2013-01-01-030405. In some situations bup get will evaluate a branch operation according to whether or not it will be a "fast-forward" (which requires that any existing destination branch be an ancestor of the source). An existing destination tag can only be overwritten by a --replace or --force-pick. When a new commit is created (i.e. via --append, --pick, etc.), it will have the same author, author date, and message as the original, but a committer and committer date corresponding to the current user and time. If requested by the appropriate options, bup will print the commit, tree, or tag hash for each destination reference updated. When rele- vant, the tree hash will be printed before the commit hash. Local refs can be pushed to a remote repository with the --remote op- tion, and remote refs can be pulled into a local repository via "bup on HOST get ...". See bup-on(1) and the EXAMPLES below for further infor- mation. WARNING: This is one of the few bup commands that can modify your archives in intentionally destructive ways. Though if an attempt to join or restore the data you still care about succeeds after you've run this command, then that's a fairly encouraging sign that it worked cor- rectly. (The dev/compare-trees command in the source tree can be used to help test before/after results.) METHODS --ff ref, --ff: ref dest fast-forward dest to match ref. If dest is not specified and ref names a save, set dest to the save's branch. If dest is not specified and ref names a branch or a tag, use the same name for dest. --append ref, --append: ref dest append all of the commits represented by ref to dest as new com- mits. If ref names a directory/tree, append a new commit for that tree. If dest is not specified and ref names a save or branch, set dest to the ref branch name. If dest is not speci- fied and ref names a tag, use the same name for dest. --pick ref, --pick: ref dest append the single commit named by ref to dest as a new commit. If dest is not specified and ref names a save, set dest to the ref branch name. If dest is not specified and ref names a tag, use the same name for dest. --force-pick ref, --force-pick: ref dest do the same thing as --pick, but don't refuse to overwrite an existing tag. --new-tag ref, --new-tag: ref dest create a dest tag for ref, but refuse to overwrite an existing tag. If dest is not specified and ref names a tag, use the same name for dest. --replace ref, --replace: ref dest clobber dest with ref, overwriting any existing tag, or replac- ing any existing branch. If dest is not specified and ref names a branch or tag, use the same name for dest. --unnamed ref copy ref into the destination repository, without any name, leaving a potentially dangling reference until/unless the object named by ref is referred to some other way (cf. bup tag). OPTIONS -s, --source=path use path as the source repository, instead of the default. -r, --remote=host:path store the indicated items on the given remote server. If path is omitted, uses the default path on the remote server (you still need to include the `:'). The connection to the remote server is made with SSH. If you'd like to specify which port, user or private key to use for the SSH connection, we recommend you use the ~/.ssh/config file. -c, --print-commits for each updated branch, print the new git commit id. -t, --print-trees for each updated branch, print the new git tree id of the filesystem root. --print-tags for each updated tag, print the new git id. -v, --verbose increase verbosity (can be used more than once). With -v, print the name of every item fetched, with -vv add directory names, and with -vvv add every filename. --bwlimit=bytes/sec don't transmit more than bytes/sec bytes per second to the server. This can help avoid sucking up all your network band- width. Use a suffix like k, M, or G to specify multiples of 1024, 1024*1024, 1024*1024*1024 respectively. -#, --compress=# set the compression level to # (a value from 0-9, where 9 is the highest and 0 is no compression). The default is 1 (fast, loose compression) EXAMPLES # Update or copy the archives branch in src-repo to the local repository. $ bup get -s src-repo --ff archives # Append a particular archives save to the pruned-archives branch. $ bup get -s src-repo --pick: archives/2013-01-01-030405 pruned-archives # Update or copy the archives branch on remotehost to the local # repository. $ bup on remotehost get --ff archives # Update or copy the local branch archives to remotehost. $ bup get -r remotehost: --ff archives # Update or copy the archives branch in src-repo to remotehost. $ bup get -s src-repo -r remotehost: --ff archives # Update the archives-2 branch on remotehost to match archives. # If archives-2 exists and is not an ancestor of archives, bup # will refuse. $ bup get -r remotehost: --ff: archives archives-2 # Replace the contents of branch y with those of x. $ bup get --replace: x y # Copy the latest local save from the archives branch to the # remote tag foo. $ bup get -r remotehost: --pick: archives/latest .tag/foo # Or if foo already exists: $ bup get -r remotehost: --force-pick: archives/latest .tag/foo # Append foo (from above) to the local other-archives branch. $ bup on remotehost get --append: .tag/foo other-archives # Append only the /home directory from archives/latest to only-home. $ bup get -s "$BUP_DIR" --append: archives/latest/home only-home SEE ALSO bup-on(1), bup-tag(1), ssh_config(5) BUP Part of the bup(1) suite.
