Prevent loss of personal data while installing CentOS linux
Hi,
My sony vaio E series machine currently runs on UBUNTU 13.10 , as i wish to move to CentOS 6.5 , is there a possible way to installing it without the loss of data, kind of formatting only the "C:\" partition in windows . |

Your personal data on a Linux system will be under /home/<your_user_name> unless you specifically stored personal files elsewhere in the filesystem. Some people put /home on a seperate partition or logical volume and then when they install a new Linux OS they simply mount their old /home in place of the newly created one. This is good for your personal data, but not always 100% workable for specific application settings (which are also stored under /home). You should still have backups though - you should ALWAYS have backups. Linux is generally much more resilient to being picked up and moved than Windows is. And Windows generally stores your personal data on it's C: drive by default, unless you manually configure it otherwise. Linux has different concepts of storage than Windows does. Windows has "drives", which equate to partitions on a hard disk. Linux has hard disk partitions too, but it also has "file systems", and optionally "logical volumes". Windows may have something similar to logical volumes by now, I'd hope they finally did that, but I haven't used Windows extensively for quite a while, and I wouldn't know about that personally. |
Hi. Personal data: I try to do backups here and there but if let it go too long spidey sense kicks in and I know my files are at risk to crash and burn and never do anything major without transfers (in my case to Blu-ray...) As far as keeping microcoughed-winblow$ :rolleyes: what version and do you have an install CD\DVD or factory reset partition if anything goes wrong? Should be able to remove Ubuntu's partition and install CentOS there plus GRUB that will detect win and be fine. Best wishes and have fun. :)

One thing I always do is create a partion table with a separate partition for home. That way I only have to reinstall any special software I want, no need to copy all my data back over. Of course, in an abundance of caution, I always put my data on my portable hard drive first.

hi,
Thanks for your swift replies fellas, but i have my data under /Pdata in sda5 , is it possible to format all other partitions except this one, if there is how do i do it? Thanks in advance. |
Is /Pdata a mounted filesystem, or just a directory under / (root) ?
|
its a mounted file system .

^ In which case, you can certainly just format other partitions (see my above post).
When you get to the partitioning part of the installer- opt for the advanced partition setup. Be sure to specify pdata5 should be used as /home. Of course, for the sake of extra safety, back everything up on another drive.... just in case. |

Personally, I would do a backup in every case, regardless of what I planned to tell the installer to do. If this is important personal data, then there is no good excuse to NOT be 100% paranoid. In the time you have taken to ask and get suggestions in this thread, you could have already completed a backup. It is good that you are asking first and not blazing ahead making assumptions that your personal data will be secure. A lot of folks do something dangerous first, out of ignorance, then come here asking for how to repair their damage. I'm glad to see you're not one of those folks. Still, my advice would be to do a backup of your personal data first. THEN see what you can do with the installer to keep it from ruining your personal data. If you succeed with the installer, great. You will have learned something and gained experience. If you don't, then you have a backup to recover from. Much better than coming back here after the fact asking how to recover with no backup available. |
