Backup portage-tree?

Hello,

I'm setting up a server and now i have a question about backing up the whole system.
I don't have too much backupspace thats why i watched arround how big my backups
will become.
I found the /usr/portage it's size is about 1.5GB . Is it a good idea to exclude it from
my monthly backups? I thought that in the beginning I will back it up once and then
never again.

If you could give me your advises...

Thanks a lot

/usr/portage is something you can just download from the web whenever. no need to backup it locally.

emerge-webrsync
emerge --sync

You could exclude most of /usr/portage from your backup. If you need to restore your server sync portage and you'll be fine. distfiles can be cleaned up from time to time. This will make /usr/portage smaller.
Keep in mind the /etc/make.profile is a link to a profile in /usr/portage

You may want to kill the source packages in /usr/portage/distfiles or use eclean to reduce the size of that directory.

But in general, loosing /usr/portage is no tradegy as ...

the portage tree itself can be downloaded via emerge --sync.
packages could be regenerated if you'd need them.
distfiles won't be a big loss too, as they're downloaded as needed during the emerge process

Thanks a lot for your answers.

I putted it in the exclude list.

If we are talking about emerge --sync...

emerge --sync updates your portage tree (ebuild).

emerge world installs updates to your computer.
