bupstash-rm(1)

Usage

bupstash rm [OPTIONS] QUERY ...

Overview

bupstash rm removes items from a bupstash repository.

Items that are removed are not immediately deleted, instead the deletion and space reclamation is scheduled for the next time the garbage collector bupstash-gc(1) is run.

Only the metadata needs to be decrypted to remove items, so a metadata key is sufficient for item deletion, even without access to the data decryption key.

Query language

For full documentation on the query language, see bupstash-query-language(7).

Remove query examples

$ id=$(bupstash put ./some-data)
$ bupstash rm id=$id
$ bupstash rm name=backups.tar
$ bupstash rm --allow-many name='*.tar' and older-than 30d
$ bupstash rm --allow-many id="*"

Query caching

The rm command uses the same query caching mechanisms as bupstash-list(1), check that page for more information on the query cache.

Options

-r, --repository REPO: The repository to connect to. May be of the form ssh://$SERVER/$PATH for remote repositories if ssh access is configured. If not specified, is set to BUPSTASH_REPOSITORY.

-k, --key KEY: Key used to decrypt metadata when executing a query. If not set, defaults to BUPSTASH_KEY.

--query-cache PATH: Path to the query-cache file, defaults to one of the following, in order, provided the appropriate environment variables are set, $BUPSTASH_QUERY_CACHE, $XDG_CACHE_HOME/.cache/bupstash/bupstash.qcache or $HOME/.cache/bupstash/bupstash.qcache.

--query-encrypted: The query will not decrypt any metadata, allowing you to list items you do not have a decryption key for. This option inserts the pseudo query tag 'decryption-key-id'.

--ids-from-stdin: Remove items with IDs read from stdin, one per line, instead of executing a query.

--allow-many: By default bupstash refuses to remove multiple items from a single query, this flag disables that safety feature.

--utc-timestamps: Display and search against timestamps in utc time instead of local time.

--no-progress: Suppress progress indicators (Progress indicators are also suppressed when stderr is not an interactive terminal).

-q, --quiet: Be quiet, implies --no-progress.

Environment

BUPSTASH_REPOSITORY: The repository to connect to. May be of the form ssh://$SERVER/$PATH for remote repositories if ssh access is configured.

BUPSTASH_REPOSITORY_COMMAND: A command to run to connect to an instance of bupstash-serve(1). This allows more complex connections to the repository for less common use cases.

BUPSTASH_KEY: Path to a primary key that will be used for decrypting data and metadata.

BUPSTASH_KEY_COMMAND: A command to run that must print the key data, can be used instead of BUPSTASH_KEY to fetch the key from arbitrary locations such as the network or other secret storage.

BUPSTASH_QUERY_CACHE: Path to the query cache file to use.

Examples

remove an item with a specific id from the repository

$ bupstash rm id=14ebd2073b258b1f55c5bbc889c49db4

remove all items from the respository

$ bupstash rm id="*"

remove items with name backup.tar that are older than 30 days

$ bupstash rm name=backup.tar and older-than 30d

remove items with a custom script

 $ bupstash list --format=jsonl1 \
    | custom-json-filter \
    | bupstash rm --ids-from-stdin
