 Posted: Thu Mar 27, 2003 4:24 am Post subject: Backup program? |
 |
|
Is there a backup program that has a Gentoo ebuild?
I want to do file backups of all my computers on my network (all 2 of them). I just really need a simple file backup (and restore) but want to do it locally and over smbfs.
Thanks

I think rsync is the best way to backup some files...(I use it too in LAN with samba shares).
you can also make a tarball...
| Code: |
cd /
tar -czvpf /mnt/backup/Gentoo_bak_201002.tar.gz / --exclude=/proc --exclude=/mnt --exclude=...
|
I've made a tarball of my root-system, /etc, /usr /bin etc. so I've the impotent files and can burn it on cd

Backups to media are good as long as you store in media off site. The best solution is for you and a buddy to backup via rsync to each other's boxes via the internet.
This will not work for your collection of music files unless you have MEGA bandwidth. However, for documents, websites, email and various config files rsync is ideal.

| tar is the original backup program. It's simple and effective. If you backup needs aren't that complicated that's what I would go with. You could even create a script and put it in your crontab. Works well with tape also. |

Is there an easy solution to encrypt your precious data with rsync on the fly? |

But this only encrypts the transmission, right? I don't want to have a backup of my data on an other (untrusted) machine, where other people could possible access this data. I would like to have my backup data encrypted on the remote machine. And I think rsync can not do this, at least not alone.
A possible approach can be to move all data (at least the part you don't want other's eyes on it) to a loop mounted crypto filesystem and then rsync this (big) file. But it would be cool if there would be a rsync like tool which encrypts data on the fly (and not decrypt it again on the remote machine). |

Sorry, I seem to have misunderstood you...
Never heard of something like that myself... I would say the only way is to use a crypto filesystem on the backup server. |

Maybe duplicity can help you?

i've used this as a backup script before:
tar cvf - ~/* | bzip2 -9 | ssh -2 -c blowfish -l username host "cat > backup.tbz2"
if you have an encryption program that can run from stdin to stdout, insert it wherever you'd like.

I just came upon the program called partimage. Together with parted I may try and make my linux partitions bigger.
Partimage claims to "Console-based application to efficiently save raw partition data to an image file. Optional encryption/compression support." |

| Boy, am I hopping on this topic late...I've been using rdiff-backup for several months and found it works well. I read that duplicity started off as a rdiff-backup spinoff. I'm installing duplicity and will fire up a few experimental backup sessions to see if it works for me. |

Hmmm, can anyone get me started with duplicity? I got all the gnupg stuff figured out, but duplicity keeps asking me for a passphrase for when I encrypt stuff...I shouldn't need to put in a passphrase for when I'm encrypting stuff...Just for when I decrypt it. Further, as an experiment, I build a key without a passphrase, but duplicity always dies instead of doing it's thing.
Can anyone get me started? There's amazingly small documentation on this project. |

rsnapshot is a great program I don't know if it encrypts though

If you are in the need of encryption for your Backups, then give "aespipe" a try.
As the name says, you just put it in a pipe and encrypt your tar's, iso's ..or whatever you wish, and the best thing, it's also in portage.
..this will do the trick.
Here's the Readme..where you find anything you need or wanna know.

I encrypt with ssl. No extra installs needed. | Code: | #!/bin/bash
#remote backup
echo "Enter openssl passphrase: "
read -s SSLPASS
cd /opt/backup
find . -type f -print |
while read file
do openssl enc -blowfish -k $SSLPASS -in $file | ssh user@foo.tld "cat > /home/nwatson/backup/$file.blow"
done
ssh user@foo.tld ls -l backup|mail -s "remote backup results" myemail@home.tld
# to decode
#openssl enc -d -blowfish -in <filename> |tar -tjf - |

Hi DeathAndTaxes,
you have to specify a passphrase on the commandline as an environment variable such as this:
| Code: | | PASSPHRASE=somepass duplicity /home file:///tmp |

hmm.. curious, I have a DVD burner in my gentoo server that I want to use to make monthly backups for offsite storage... is there a DVD burner app that is command line friendly?
I would like to have it run from a cron script, it would only have to burn a simple 200MB tar file, and leave the disc open for the next months burn. |
