ok well on my Amon Ra Recovery.
there is an option for nandroid back up and theres another
option about nandroid + ext backup.
i think thats it.
but i have no clue what nandroid +ext backup.
what does ext mean? extension?
whats the extension for?
and there other options are google proprietary files back and restore.
what the heck is that?
please some give me answers.
it is for people have an multiple partitions on their SD card. ext is a type of partition
The ext partition is a linux partition type used by Dark Tremor's a2sd. Basically, if your custom rom supports a2sd, you can extend your apps installation space by creating an ext 2 (can be upgraded to ext 3 and 4) partition on the sd card besides the normal fat32 partition. If you don't have an ext partition, just do a simple nandroid backup. Otherwise do nandroid + ext backup if you do have one.

how do i do it
i booted into recovory mode
and clicked partitions menu
but i dont see partition sd card
just format sdcard
Not following the previous, but related
Rom Manager gives me the option to partition my sd card, but informs me that will wipe my card. I have Titanium backup, but I assume the backups are stored on the sd.
I am being cautious, which is probably causing me to ask a noobie question of offensive ignorance, but is Titanium backing up what is already in my ROM?
If so, no problem on the repartition, just back up again after reformat...
Next question: what is the best suggestion for partition size on an 8 gb card? And What is the best swap size for performance?
Thanks for any answers!
Hi,
In the next few days, I will receive a new 8GB SD for my HTC Desire. But sice I'm using A2SD+, I'm wondering how I could migrate all the data + partitions to the news card? I'm aware I have to partition my new card first, but how is it possible to duplicate and copy the contents to my new card? I'm mainly concerned about the data on the 2nd partition, where all my apps are installed...
1.Do a nandroid backup of the existing rom with old card
2.Partition the new sdcard
3.Restore nandroid with the new sdcard
Nandroid will backup and restore the sd-ext partition also.
I would use gparted.
plug both sdcards in your PC
delete the partition on your new sdcard
copy both partitions over from your old sdcard
resize fat partition to fill the free space if your new sdcard is bigger
this way is quicker and easier in my opinion.
gparted is included in the ubuntu livecd if you've got one lying round. if not you can get a gparted live cd com the internets.

imo its easer just to do a nandroid, put the new sd card in and use the advanced restore to restore the ext
thanks for the replies. So to partition, should I use the recovery to partition or can I use my computer (mac os x), since it's a linux partition that I need.
I didn't know that nandroid backup also backups my apps on the 2nd partition?
Is it also possible to use Titanium backup?

probably is, but i use linux on my desktop so its no hassle for me...
last time i did a nandroid of my ext partition i lost everything else on the partition (I use it for extra sdcard space and i've got debian installed there also.) the apps were saved but it didnt backup anything else on the ext partition, but i suppose this isnt a problem for most people.
Hello. Silly question. I'm gonna partition the sdcard, so I want to back it up first. Is it as simple as copying all the sdcard onto my hard drive, then restoring all the folders again after the format? Everything should be back to normal and nothing would go wrong?
Exactly that
Well that's convenient =).
Thanks EddyOS.
One thing to mention - are you already using an EXT partition? If so, this can't be backed up in Windows so you'd need to do a nandroid OR backup it up in a linux install
If not, then continue as you are
Yup I know. I'm backing up the sdcard because I'm going to partition it to Fat32 + EXT, so I'll just restore the backup to the Fat32 partition. Also, should I partition it to EXT3 or EXT4?
Depends on the ROM, I use EXT3 and its fine for me
I've a 8 GB sd card, but now a new one 16 GB. On my 8GB I've got a partition with a lot of stuff ( Apps! ) but how to copy them to the new SD card? I've got Amon ra recovery. So a new partition I can make. But with backup you can choose nand or nand + ext. I have chosen the nand + ext. But you can only restore the nand. So how to restore the ext too?
The ext Will also be restored, just make sure that The new Card has been made with The same ext size or bigger.
Don't why but I got stuck on the boot animation.
Partition the card with Gparted and try again.
I realise that I should have created my ext partition as ext4 not ext3 as the newer roms seem to need it. I had a search and it seems to be a bit complicated to simply convert the partition so I have a two-part question to see if what I have in mind will work.
I use Link2sd which I like and seems to work well (other than for Swype which I now have gotten rid of).
So, will this work (and I apologise for being somlistic in my approach):
I move all my linked apps to the SDcard proper using L2SD (there's not enough room on the phone's internal memory)
I copy my entire SD card to my computer just in case
I then use 4EXT and using the option "wipe or format --> EXT3" I reformat that ext3 partition as a ext4 partition
Using L2SD I relink all the apps to the new ext4.
Otherwise, if I were to reformat and repartition the entire SD card using Gparted, can I simply drag and drop the SDcard folder I backed up on my computer back onto the SD card then relink everything with L2SD?

Great - nice and easy. Should I move the apps to the main part of sd card first by unlinking them because I don't see the ext3 partition when I connect the phone to my computer.
The concept of doing a nandbackup is to copy thhe current status of the phone. Everything. So you relly don't need to do that.
Just make sure that the contents you see when you plug the phone to the computer is saved in the computer including the nandbackup you made.
The nand will basically take care of the files on the ext part when you restore it.

If using 4ext you only need to convert ext to ext4(it backs up automatically). If you restore a nand made with ext3 you also loose the ext4 partition so you also need to manually convert all nand backups to ext4 using 4ext. Hope this makes sense...

It makes sense but I'm starting to get a bit confused as to what I now need to do.
What you're saying is the nand backup will put the phone back how it was to start with, ie the ext4 partition will revert to ext3? So what is the best way to do all of this? When you say "you also need to manually convert all nand backups to ext4 using 4ext. " how do I do that and do you mean before or after I restore the nand backup?
To make this easier, can I not simply forget the nand backup and do this: unlink all my apps with L2sd and put them onto the sd card like in native apps2sd. Then put the whole sd card on a folder on my computer, wipe and repartiton the sd card with ext4, move the whole folder back onto the fat32 partition and the use L2sd to relink all the apps onto the new ext4 partition?

Put simply:
boot into 4ext recovery.
go into tools/Convert or change a backup --> ext4
convert ext
It will automatically backup ext, convert it to ext4 and then restore ext again (no data loss).
Delete all old NAND backups and start again (otherwise you'll restore your ext3 partition) or you can convert backups with 4ext (from ext3 to ext4).
Simples :victory:

Absolutely brilliant - thanks! Done that and it worked.
How do I delete an old Nand backup - I'm looking in 4ext but can't see anything obvious or do I simply do another backup and that wipes the old one?

Using the 4ext app go into manage backups or using a file explorer go into sdcard/clockworkmod/backup and delete the corresponding folder

I have booted the phone up but now it does not want to recognise the ext partition. Links2sd suggests that the device may not support ext4 yet I know lots of Desire owners on here have that. I guess I have to revert to get my apps back that are currently showing as not loaded.
Just convert back to ext3 again using 4ext.. kernel might not support ext4

Damn. Oh well, thanks for the help anyway.
Anyone know what kernel I would need and how would I go about installing it? Is this a fairly easy and safe thing to do?

I'd say just leave it as ext3. I've never come across a ROM that don't support ext3....

I was thinking of installing this one: http://forum.xda-developers.com/showthread.php?t=1315961 I hear it is quite a stable one and that's most important to me. It says that ext4 is required for the ROM:
(Q) I get an error ”can’t Mount /dev/block/mmcblk0p2 (File Exists)”.
(A) That error and others like it are generally caused by a corrupt ext partition on your SD Card. The solution is to use 4EXT recovery, gParted, or a similar tool to reformat the ext partition to ext4. Leave the FAT32 partition alone and you shouldn’t lose any data. Don't use Windows-based partition tools!
Some suggest using ext3 as it is a known quantity and most ROMS will boot with an ext3 partition, however Runnymede AIO requires an ext4 partition.
and for AD2SDX to work (links you to here: http://forum.xda-developers.com/showpost.php?p=18911182&postcount=1784 )
I'll have to look for another instead.
