Accessing Swestore with rclone

< Swestore-dCache

This guide describes how to use the Rclone WebDAV client for storing and retrieving files from Swestore. Rclone is versatile and supports many protocols through a simple command line interface (CLI).

Requirements

To access Swestore using the rclone you need to be a member of a Swestore storage project, see Swestore#Getting access to Swestore.

You also need to know your Username and password, see Setting your Swestore password.

To install rclone on your own computer, please follow your systems instructions at the official rclone documentation pages here.

Quickstart

Swestore access URL

The WebDAV access URL for Swestore should be specified for rclone as;

https://webdav.swestore.se

Basic commands

rclone config - configure rclone. See Rclone configuration for details.

rclone ls - for listing files. Works similarly to ls. See Rclone ls.

rclone copyto - for copying directories or separate files. Works similarly to cp with wildcards. See Rclone copyto.

rclone copy - for copying contents of directories. Works similarly to cp -R path/*. See Rclone copy.

rclone mkdir - for creating directories. Works similarly to mkdir -p. See Rclone mkdir.

rclone deletefile - for removing specific files. Works similarly to rm. See Rclone deletefile.

More powerful removal functions are available, but be careful with these;

rclone delete - for removing all files under path - i.e. you loose your data. Works similarly to find path -type f | xargs rm. See Rclone delete.

rclone rmdir - removing path if empty. Works similarly to rm -d. See Rclone rmdir.

rclone rmdirs - removing all empty directories under path. Works similarly to find path -type d | awk '{ print length, $0 }' | sort -nsr | cut -d" " -f2- | xargs rm -d (example modified from stackoverflow). See Rclone rmdirs.

rclone purge - removing all data under path, including path - i.e. you loose your data. Works similarly to rm -rf. See Rclone purge.

Use man and --help to get more info on rclone and its commands. Examples: man rclone, rclone --help or rclone copy --help .

Paths

The rclone commands supports multiple storage protocols. Given that you have configured https://webdav.swestore.se as the swestore remote, we recommend using WebDAV with paths on the form swestore:/snic/YOUR_PROJECT_DIR/... .

Configuration

You have to configure rclone with your access protocol, URL and user login credentials for it to work. Simply issue the following configuration command to interactively configure rclone;

$ rclone config

For configuring WebDAV, this amounts to answering something along the lines;

n for New remote

swestore for name

webdav for Storage (or the corresponding number in the list)

https://webdav.swestore.se for url

other for vendor (or the corresponding number in the list)

yourusername for user, should be on the format s_user

y for Yes type in my own password

then enter your swestore password twice

Just press <Enter> for bearer_token

n for Edit advanced config?

y if you think the resulting config is correct, otherwise e to edit again.

q to Quit config

To see your configuartion afterwards, run

$ cat ~/.config/rclone/rclone.conf

You can also list your configured remotes by issuing

$ rclone listremotes

In the following sections, we are assuming your swestore remote is named swestore

Copying files

Copying files to and from resources is accomplished using the rclone copy and copyto command.

Copying single files

Copying single files is accomplished in the same way as using the normal cp command as shown in the following example:

$ rclone copyto archive.tar.gz swestore:/snic/YOUR_PROJECT_DIR/archive.tar.gz

You can also use copyto in order to rename the file in the process of copying it to the destination, by specifying a different filename on the remote.

Recursive copying

Recursive copying of a directory is accomplished using the copy command. The command will only copy files that have changed on the source compared to the destination, which is determined by checksums and timestamps. Observe that the source directory is not copied over, only its contents. Also, empty directories are omitted.

Example:

$ rclone copy /path/to/src swestore:/snic/YOUR_PROJECT_DIR/DESTINATION_DIRECTORY

The option --no-traverse can be used to not list files on the destination (good for huge directories). --max-age can be used to select the most recently modified files for transfer, and -P gives you status on progress.

Example, copying the last days modifications, with progress:

$ rclone copy --max-age 24h --no-traverse -P /path/to/src swestore:/snic/YOUR_PROJECT_DIR/DESTINATION_DIRECTORY

NOTE: The above example will copy all files in the directory src into the destination directory DESTINATION_DIRECTORY. If you want the directory src to be part of the destination path you have to explicitly supply it as shown in the example below:

$ rclone copy /path/to/src swestore:/snic/YOUR_PROJECT_DIR/DESTINATION_DIRECTORY/src

Listing

Rclone supports listing all files under a path.

Listing files and directories on a resources is done using the ls or one of the ls* commands (see below). The simple ls command only lists objects and their sizes in the specified directory and all subdirectories due to recursion being enabled by default.

$ rclone ls swestore:/snic/YOUR_PROJECT_DIR

Further functionality can be be achieved from using any of the the following ls* commands;

lsl long listing with additional info

lsd list only directories

lsf list objects and directories, in a fashion good for scripting

lsjson gives advanced output in JSON format

NOTE: The ls and lsl recurses to show all subdirectories by default - use --max-depth 1 to disable it. For other commands you need to specify the -R flag to enable recursion.

Examples:

$ rclone lsl --max-depth 1 swestore:/snic/YOUR_PROJECT_DIR

$ rclone lsd swestore:/snic/YOUR_PROJECT_DIR

Creating directories

Directories are generally created on demand. If you copy a file with the destination /snic/YOUR_PROJECT_DIR/newdir/dummyfile the newdir directory will be created if missing. But you can explicitly create directories using the mkdir command.

$ rclone mkdir swestore:/snic/YOUR_PROJECT_DIR/newdir

Removing files or directories

Beware that the command delete will recursively delete all file objects under specified path!

To remove the file dummyfile under /snic/YOUR_PROJECT_DIR/newdir,

$ rclone deletefile swestore:/snic/YOUR_PROJECT_DIR/newdir/dummyfile

To remove a directory, they have to be empty, and you use the command

$ rclone rmdir swestore:/snic/YOUR_PROJECT_DIR/newdir/

To remove all empty directories under a path, use

$ rclone rmdirs swestore:/snic/YOUR_PROJECT_DIR/newdir/

To recursively remove all files under /snic/YOUR_PROJECT_DIR/newdir, leaving the empty directory structure in place, be careful;

$ rclone delete swestore:/snic/YOUR_PROJECT_DIR/newdir/

Do not use the command purge, as that will delete everything under the path specified.

FAQ

Q: I used rclone purge or rclone delete and have now deleted all my files; can I get them back somehow?

A: No. Swestore does not currently support recovery of data for which the user has explicably requested to be deleted from the system, be it intentionally or by mistake. Therefore caution is advised while using powerful tools such as rclone.
