Do I need to backup harddrives before install lion

Do I need to backup hardrives before installing lion, on mac-pro. I have tons of pictures and video, and 2 harddrives, i have some on external hard drive, but not current stuff, and wanting to upgrade to Lion. Please advise. I am sure most are going to say back up, back up. I guess I want to know if I will lose pics, documents, mail, if I upgrade.

That's a bit like asking, do I need to wear seatbelts? Seriously if you value your data, you need to backup your data, not just when installing Lion, but when installing anything, when making changes to your data, when renaming data. Backing up is not an option, it is a must in the computing world. See my backup FAQ*:

You could, in fact in one thread, someone backed up with Time Machine, and still lost pics because they didn't ensure their Time Machine had in fact backed up the pictures they wanted. A clone backup is the only backup that ensures everything is backed up. Anything can be lost in an upgrade too. See what I have to say about other Lion pitfalls:*

Do I have to do anything to my harddrive before installing lion?

I want to clean install Lion OS X using lion recovery HD (the one that you have to push command+R at startup). Everytime I try to install a brand new clean copy, when I get back to the computer I find it restarted to my old desktop. Do I need to erase the items using Disk Utility before installing a new version?

Yes, by default the installation just replaces the OS and doesn't delete any of your data. If you want a clean install, erase the partition with disk utility.

I have created a new partition on the Mac HD for Lion as I would like to dual boot. Do I need to install Snow Leopard on that partition before installing Lion? If so, can I use one of my Time Machine backups to do this?

Can I set up 2 different time capsule backups? one for the lion partition and one for the snow leopard partition?
No, you can't partition a Time Capsule's internal HD. Both partitions will back up to the same sparse bundle. keeping the backups for each partition separate.
Time Machine will not take the two OSX partitions as two different computers, but for best results, exclude the Snow Leopard drive from backups on the Lion partition, and exclude the Lion partition from backups on the Snow Leopard partition.
There may be some files on the Lion partition that Time Machine on Snow Leopard won't like, among other things. See #10 in Time Machine - Frequently Asked Questions for details.

Does earlier version of elements need to be uninstalled before installing PSE13?

does earlier version of elements need to be uninstalled before installing PSE13?

Hello,
don't worry, I for my part I have on my computer more of these earlierer (outdated in some cases) Adobe programs, to see the difference or for some other reasons. Try them out for a while and then decide, whether you need the both.

Do I need start the database before installing Oracle 9iAS portal?

I found the Oracle white paper which talks about installing
Oracle8i EE and Oracle 9iAS portal on windows 2000. Based this
document, after Oracle 8i installaion but before installing
Oracle 8.1.7.1.1 path, all the Oracle database related services
startup type have been changed to 'Manual'.
Based on my understanding, there are some objects will be
created in this database during the installation of 9iAS portal
repository. But this oracle white paper didn't say that I need
have the database ruuning during the 9iAS installation. Do I
need to start the database before installing 9iAS?
Thanks

hi,
Even i am new to oracle application server and had the same doubt that you have.
When you install Application Server there would be two tiers installed, application tier and middle tier, these tiers can be running from the same machine or different machines.
These tiers will have a meta data repository to store application server related data, this database will be installed along with application server.
It is upto you to install "oracle database 10gR2 " before or after installaion of application server, this will be an independent database which will have its own home, but after this installation you will have three homes, ex: infra_home,mid_home and 10gR2_home.
by default oracle_home is set to the last installation that happens so if you install the database 10gR2 after installing application server it will point to 10gR2_home, but if you install 10gR2 before and application server later then the oracle home will be infra_home(if both the middle tier and infratier are on the same machine)
you can always change the oracle home by using set ORACLE_HOME=path/to/oracle/home( in windows)
or export ORACLE_HOME=path/to/oracle/home (in unix)
hope this helps....
regards

I am running Mac OS X and need to back up before installing Snow Leopard , can I back up to my Time Capsule?

I am running Mac OS X currently and need to upgrade to Snow Leopard. First I need to back up my computer. I have a Time Capsule that automaticallyt backs up Snow Leopard and above but do not have Time Machine on this system. How can I back up what I an currently running?

Do I download these? I am not particularly good at this, so any help would be great. What I know now is that it is recommended to back up current comuter before installing snow leopard, but I have no idea how to do this. I know I can go from 10.4.11 directly to Snow Leopard but am afraid I will lose data.

Do individual Adobe products need to be uninstalled before installing creative cloud?

I am deploying user licenses to several users in a department where a lot of individual Adobe products are installed and already in use. Will these individual products need to be uninstalled before using or installing Adobe Creative Cloud?

U-96,
When you install different versions, you should always do so in order from first to last. With a different order, you will (almost certainly) overwrite crucial files with older versions.

Already have Support Software v5.0 installed, do I need to uninstall it before installing SS v5.1? Please help!

as title.

thanks for reply.
anyway, I uninstall the older version before installing the new. for those who having trouble uninstalling Windows software try Fix it software from microsoft (thank rtheb's post).
one thing I didn't mention is that I did a fresh win8 install using boot camp assistant, but at that time the latest boot camp support services available was v4.0 which is not supposed to support win8.
later, when boot camp support services v5.0 final was released, I installed it on top of v4.0 (i.e. without uninstalling v4.0). I couldn't remember if I got a error message for that, but the computer seemed running ok except that I got a error message when uninstalling boot camp support services v5.0 this time.

Do I need to uninstall CS5 before installing Cloud Versions?

I'm a new cloud user and haven't downloaded the software yet. Do I need to uninstall CS5 before downloading the cloud versions?

No need to uninstall unless you want to. Major versions can co-exist.

Do I need to uninstall FCP before installing FCP Studio 2?

Hi all, I have Final Cut Pro Studio, FCP 5.1.4, Academic version, and recently got Final Cut Studio 2, and just wanted to check to see if I needed to completely reinstall FCP, or would just installing FCP Studio 2, do the trick?
Thanks

I'm still trying to figure out my plan of attack for installing FCS2 when it arrives today.
Randy, do you at least delete the apps before installation, or do you just put the DVDs in and go?
Most folks around here preach the complete reinstall of the OS and then installing FCS2...you don't agree?
Just trying to get all opinions here...you are cleared of any blame when/if something goes wrong!

Need to repair HD before installing mavericks HELP !!

Dear all,
I have a perfectly working MacBook Air, built 2012 with 256 GB.
Mountain Lion does a great job, but I want to progress to Mavericks.
As advised, I ran disk Utility system check and this came up at veryfying disk:
Volume bitmap needs minor repair for orphaned blocks
Invalid Volume free block count
The Volme MA_HD was found corrupt and needs to be repaired
As advised I restart holding the command-R combo after which my computer starts to connect to the Internet searching for the boot-tool. then after about 30 seconds, I get a warining sign with apple.com/support - 1007F.
When I am on another network, the Internet logo keeps spinning for 20 minutes and then I get a -2007F failure.
I can not repair my disk it seems, although all is working fien.
Quickly made a Time Machine backup, but what can i do next ?
thanks for your help !!

Same thing: Internet logo spinning for 10 seconds, then apple.com/support -100F.
In the meantime the computer works perfect under Mountain Lion.

Do I need to uninstall CS4 before installing CS6

Hello
I'm looking at upgrading from CS4 to CS6. Is it best practice to remove CS4 first? My concern is all work created in CS4 may have computability issues with CS6 and perhaps keeping CS4 around isn't a bad idea as a safety net...

It is not a requirement to uninstall CS4 when installing CS6. As far as upograding from CS4 to CS6 goes you should doublecheck if that is possible. For products that I am aware of there is no longer an upgrade path from CS4 to CS6, only CS5+.

I currently have LR5 and PS Elements on my Mac. Do I need to uninstall LR before installing CC?

Do I leave the current version of Lightroom on my computer and just register it with Lightroom mobile?

Thanks for confirming that. One problem I have is that Lightroom has made Photoshop Elements the default external editor. I have Portrait Pro as the second editor, so I can't integrate Lightroom with Photoshop. I've read elsewhere that if I uninstall Photoshop Elements, Lightroom should pick up Photoshop as the external editor.

Do I need to uninstall Safari before installing Firefox?

I have a Mac running Leopard and an iPad.

Thank you so much for your quick response. That's good to know. I'm sure iPad will continue to improve as far as Apps go.

Re: Must install Snow Leopard 1st Before Installing Lion

I am about to purchase Snow Leopard in order to enable Lion download/installation. Before I do, is there any reason to believe this step will be unnecessary within a short period of time?

No. Having SL installed is necessary so you can access the Mac App Store in order to download Lion.
