Re: [Emc-users] How to re-enable updates
I highly recommend to keep all configs under source code control like CVS or subversion. Just a side note. I like your plan on what to back up. I think that you will be fine. If you feel extremely cautious, just buy yourself another hard drive and keep the old hard drive. i On Tue, Jun 21, 2011 at 12:56 PM, Karl Cunningham wrote: > I am working on an emc2 2.4 system that was installed with Ubuntu 10.04, > but a distribution upgrade to 10.10 was done by mistake about 6 months > ago.

Re: [Emc-users] How to re-enable updates
Version control for the win. I'm a huge believer in "git", but there are others that will work fine, especially for single user stuff. You can also use something like Clonezilla to make an image of the existing drive, which can be restored if disaster strikes. -Pete On 06/21/2011 11:04 AM, Igor Chudov wrote: > I highly recommend to keep all configs under source code control like CVS or > subversion.

Re: [Emc-users] How to re-enable updates
One thought, that others will undoubtedly shoot down, For your 'temporary backup' solution, install dropbox. Put the files you want in there. Re-install your machine, then put drop box on and get your configs back. Then if you want, un-install dropbox. Or use ubuntuone. Both have 2G for free. Don't consider this 'safe storage'.

What I've done before for these kinds of things is use tar and netcat to copy the file system to another machine on the local network. And for peace of mind I'll also make a copy of the home directory to a flash drive. Shouldn't need any offsite storage. Thanks to all for the suggestions. My main concern was due to my lack of experience with emc2, and not knowing if I was going to need anything other than in /home. And thanks for the idea about the version control system for the configs. Karl -- EditLive Enterprise is the world's most technically advanced content authoring tool.

Re: [Emc-users] How to re-enable updates
Actually, if you can afford another disk drive, put in a new drive, install on it. Then install your old drive as a 'second' drive, and copy your config files over. This way you can keep the old drive for a while after you get things running. Out of the machine is best to ensure nothing happens to it. After a while, get a USB external drive box and put the old drive in it. Then you can reformat it, or whatever you want. Makes for good portable back up media if nothing else! ... Currently, I do this whenever I build a new machine when I can. Yes, I use the old drives as offline backups, 'transportable' drives, and even as extra storage for both Linux and Winders machines. Using crashplan I backup all my machines (windows and linux, multiple of each) to one USB external drive I keep on on e Linux machine. All boxes are onsite (on our wireless lan). It works pretty well. Just a few thoughts. -- EditLive Enterprise is the world's most technically advanced content authoring tool.

I then just use rsync to mirror anything that doesn't come with the distro or from apt-get. To be able to say to myself "Yes, it _is_ backed up.", the script then runs "diff -qr" to check every byte backed up. Another script backs up to flash sticks, of which I use 4, so I can go back as far as a month, a week at the time, if needed. Now a hard drive can curl up its toes, and I keep truckin'. [1] The whole PC can go west, and I'm only set back a few days. It is my belief that data which exists in only one place actually exists only in our imagination. Erik [1] The second drive retains the previous OS version, so that moving to each new release is toe-dipping, rather than a dive off the deep end. -- Real Men don't make backups.
