 After #21304, in the [http://meetbot.debian.net/tor-meeting/2019/tor-
 meeting.2019-04-18-20.01.log.html 2019-04-18] team checkin, we agreed to
 delete the pre-sanitization logs by 2019-06-01. Before then, we have a
 chance to extract any useful sanitized information from them.

 Cf. comment:8:ticket:30125 regarding the location of logs.

 === Broker

 On the broker, there are three files to delete:

  /var/log/snowflake-broker/unstanitized.tar::
    Contains three files:
     * '''unsanitized.tar.1''', pre-rotation logs from 2017-07-15 to
 2019-03-22 and rotated logs from 2017-03-22 to 2019-04-16.
     * '''@400000005cb771341453839c.s''', logs from 2019-04-16 to
 2019-04-17.
     * '''current''', empty file.
  /var/log/snowflake-broker/mv:: Probably the result of a typo, it is a tar
 file that contains a single file '''unsanitized.tar''' which is identical
 to the '''unsanitized.tar.1''' inside '''/var/log/snowflake-
 broker/unstanitized.tar'''.
  /var/log/snowflake-broker/x.tar:: contains a subset of what '''/var/log
 /snowflake-broker/mv''' contains.

 I think the most complete logs come from '''/var/log/snowflake-
 broker/unstanitized.tar''', extracting the contained
 '''unsanitized.tar.1''' and combining it with the contained
 '''@400000005cb771341453839c.s'''.

 === snowflake-server

  /var/log/tor/unsanitized.tar:: contains rotated logs dated 2019-02-18 to
 2019-04-11.

 === proxy-go

  /home/snowflake-proxy/unsanitized_old.tar:: contains 31 individual log
 files:
   * snowflake-proxy-17h.log
   * snowflake-proxy-23h.log
   * snowflake-proxy-29h.log
   * snowflake-proxy-restartless.log
