The gs_rsync
function makes the contents under destination
the same
as the contents under source
, by copying any missing files/objects (or
those whose data has changed), and (if the delete
option is specified)
deleting any extra files/objects. source
must specify a directory, bucket,
or bucket subdirectory.
gs_rsync(source, destination, delete = FALSE, recursive = FALSE,
parallel = TRUE, dry_run = FALSE, options = NULL, echo = TRUE)
The file to be copied. This can be either a path on the local
filesystem, or a Google Storage URI (e.g. gs://[BUCKET_NAME]/[FILENAME.CSV]
).
The location where the source
file should be copied to. This can be
either a path on the local filesystem, or a Google Storage URI (e.g.
gs://[BUCKET_NAME]/[FILENAME.CSV]
).
Delete extra files under destination
not found under
source
By default extra files are not deleted.
Causes directories, buckets, and bucket subdirectories to
be synchronized recursively. If you neglect to use this option
gs_rsync()
will make only the top-level directory in the source and
destination URLs match, skipping any sub-directories.
Causes synchronization to run in parallel. This can significantly improve performance if you are performing operations on a large number of files over a reasonably fast network connection.
Causes rsync to run in "dry run" mode, i.e., just outputting what would be copied or deleted without actually doing any copying/deleting.
