Scrubber

Scrubber provides an easy way to clean up old files in a directory.

It is especially useful on platforms where logrotate is not easily available or disk space is sparse.

Configuration

You can specify directories to clean up in a toml configuration file. You can define one or more strategies used for each directory.

title = "Log scrubber example config"

[[directory]]
name = "Apache Logs"
path = "/var/logs/apache"
exclude = ["zip"]

    [[directory.strategy]]
    type = "size"
    action = "delete"
    limit = "100M"

    [[directory.strategy]]
    type = "age"
    action = "delete"
    limit = "1y"

    [[directory.strategy]]
    type = "age"
    action = "zip"
    limit = "1d"

[[directory]]
name = "Backups"
path = "/var/backups/yourapp"
include = ["tar.gz"]

    [[directory.strategy]]
    type = "age"
    action = "delete"
    limit = "1y"

Directory

The following options are available for each directory:

Option	Description
name	A descriptive name for this directory.
path	The full path to the directory. Can be a Glob expression (like /path/*/subfolder).
include	(Optional) Define what files should be included. All files without a matching extension will be ignored.
exclude	(Optional) Define what files should be excluded. All files with matching extension will be ignored.
keep_latest	Any , leave the latest n files untouched.

You can either specify a include or a exclude rule but never both.

Strategy

The following options are available for each strategy:

Option	Possible values	Description
type	age and size	If the files should be selected by their age (last modified) or their size.
action	delete and zip	If matching files should be deleted or zipped. The zip action will remove the original file. Make sure to also exclude zip files from this rule so created zip files won't be cleaned up on subsequent runs.
limit	A file size or age	Define the max. age as 1y, 1d, 2h or the file size as 1M, 1GB, 1000B. Supported units for the age are m, h, d, w, y. Supported units for the size are B, KB, MB, GB, TB, PB.

Run

You can run scrubber from the command line. The following options are available:

Param	Default	Description
-config	scrubber.config.toml	The path to your configuration file.
-pretend	false	If specified, scrubber will log actions but not execute them.

# Check your config and see what will be done
./scrubber -config scrubber.config.toml -pretend
# Execute the action
./scrubber -config scrubber.config.toml
