I have been creating a local mirror of the CRAN for my works servers.
After a review of the CRAN mirror literature, I settled on the following
command to perform the mirror:
rsync -rtlzv --delete --exclude-from u:\CRANRSYNCFilterRules
cran.r-project.org::CRAN .
Where the CRANRSYNCFilterRules file has the following contents:
/ BEGIN SNIP
- bin/linux
- bin/macos
- bin/macosx
- bin/windows/base/old
#- bin/windows/contrib/*
- bin/windows/contrib/1*
- bin/windows/contrib/2*
- bin/windows/contrib/3.0
- bin/windows/contrib/3.1
+ bin/
+ bin/windows/
+ bin/windows/contrib/
+ bin/windows/contrib/3.2/
+ bin/windows/contrib/3.2/***
/ END SNIP
What I find is that the command tends to redownload a lot of files and I
can never seem to get past the windows/contrib/3.2 directory because I have
to leave work and go home for the day after 7 hours. Is there something
incorrect with my rsync command which is forcing the redownload of a lot of
packages? Is there a way to speed this process up? Thank you for any help.
No, we rebuild really many packages on a daily basis. Once a depdendency
changes you may need to build a new binary. So this is expected.
Best,
