backup LVM LV with bup

Bup is a backup software that use git for the storage. Bup import chunks of file to deduplicate large files.

tosh-r630:~/backup$cat /dev/mapper/virtualmachines-sarge | bup split -n virtualmachines-sarges
bloom: adding 1 file (10967 objects).
tosh-r630:~/backup$bup join virtualmachines-sarges > /tmp/sarges.img
tosh-r630:~/backup$file /tmp/sarges.img

OpenSSL1.0.0e+Net::SSLeay on Windows

I managed to get Net::SSLeay to work with the last OpenSSL release. Here just some not for myself.

OpenSSL test-suite build will fail but the .a and the openssl.exe file are ok.

The openssl.exe binary is in apps/ on Windows, not bin. Net::SSleay Makefile.PL file to find the OpenSSL distribution because of that.
