What is the current (2017) approximate (+/- 50Gb is adequate precision) size of the CTAN mirror ?

I cannot find this information online, the only way to calculate it myself seems to rsync, but this is exactly what I want to know before committing to it. Michael Doob' Mirroring CTAN article from year 2001 is obviously outdated, it states that the mirror takes 5Gb, which is clearly no longer true because TeXLive DVD is there.

Update: 32Gb, apparently.

    Welcome to TeX.SX! +/- 50 GB? Probably 5 Gb is correct then.

    The page ctan.org/ctan says "You will need about 50 Gb of hard disk space" to be a mirror. Apr 20, 2017 at 10:44
  • If I remember well, if you run rsync with -n option it does nothing, but gives you the result with the size.

  • I remembered well: if you run rsync with -n option (--dry-run), it doesn't do any file transfers, instead it will just report the actions it would have taken. See here: ss64.com/bash/rsync_options.html

    So, given the criterion of +/- 50 Gb, the size of a CTAN mirror is 0b.

Ulrike already has quoted the official page on CTAN.

In addition I can say that currently 34Gb of the requested 50Gb are effectively used. This leaves some room for growth.
