If I check compression and skip md5 sum, will it make the total size of my backups smaller? Is there any disadvantages to this? Also, do I need to backup the cache?

Can anybody help me out with this?
I have never tried it. But they are already zip files so I'm thinking they aren't going to get smaller. Also you can backup the cache if you want but it's not required. I don't ever backup cache.

Compression will definitely shrink the size of your backups but will make it take much longer. I have not done a comparison of size lately to give you a good estimate.
MD5 sums are good for verifying the integrity of the backed up file and don't use a significant amount of space, because it's just a short string of text.

Running Beans 5 a typical nandroid with no compression 3.1 GB, and 2 GB with compression. Compression also doubles backup time to 11 minutes. I do not use MD5 , but it is used to verify integrity of nandroid file at time of restoration (makes sure file is not corrupted). MD5 will add 1-2 minutes to backup time. Times are using 64GB sandisk extreme microsd card.
Thanks for all your input. From all the info you gave me, I will not backup cache, I will compress and I will use md5 to be safe.
Edit:
Fixed my issue.

So, if I have a ROM (CMYLXGO's Stock Desire) w/ 425 MB system partition and I back it up with CWM , then install another ROM with 150MB system partition (installing the 150MB partition prior to install of course), do I need to repartition back to the 425MB prior to restoring the 425MB partitioned backup?
Common sense would tell me yes, BUT, I figured I would ask just in case I am wrong!

Yes, you definitely need to re-partition.
Thank you - thats just what I needed to know!

What will be the problem if i dont perform repartition?
I had been wondering if a nandroid backup would restore old partition sizes, since it backs up everything, but yeah i guess it makes sense that it can't change the size of the recovery partition, since that's what cwm is running from at the time of backup/restore. But does nandroid restore system and cache partition sizes?

No, the restore just loads the partition contents into the partition, it doesn't adjust the sizes, or recreate them,, just loads the backed up contents into it.
ive been reading/looking on how to install CWM
Just saw this one on youtube
but havent tried it yet
i dont know if the firmware version matter or not..
any testers??

easy steps right?
I used the same method to install cwm on my phone. It works

just backup my stock rom.
it was running and..
NO sd-ext found, skipping backup of sd-ext
generating md5 sum...
backup complete!
whats the meaning of no sd-extension found?

Not sure about that. Guess , if we use link2sd or other programs to move some programs to sd card , the cwm backsup data relating to those programs else it shows the above message , not sure though .

Because CWM is prepared to make full backup phone. Including SD-EXT partition if you had ...
But you do not have, it simply does not backup that part and continuous.
But the backup is OK.
I have backed up my N7 two different ways, and am a little confused as to the differences in size, and *what* exactly is backed up. The first method I tried, because my N7 is encrypted, was the ADB backup method. Using the following:
adb backup -f C:\XXXXXX.ab -apk -shared -all -system (which is every option), get's me a backup of about 2.2 Gigs. I have 1.5 Gigs of Co-pilot maps, and about 600 Megs of video, in addition to apps and the system.
When I do a TWRP backup (now that it supports encryption), using *all* the options (3 are checked by default, and I add the rest like Cache, Boot, etc...) I get a backup of about 1 Gig.
Coming from the Windows world and having one image that includes the entire computer system, I want the same thing for the N7: Disaster occurs and I just recover 1 image and have everything back the way it was. Why the size difference between the two? Which one is more complete? Best for a disaster/replacement after loss/theft?
Thanks!

Twrp and cwm compress their backups. Which is more secure? Well if they're both on the disk and it's encrypted I would think both, I'm not sure if encrypted backups are supported.

In case its helpful, the new TWRP version has some new features for doing encrypted backups.

Thanks for the replies. I'm not worried about the security (the ADB backup is encrypted by default. and the TWRP backup is stored in a TrueCrypt container). I was more concerned with the size difference. It looks like the TWRP backup might not include the GPS maps or my videos? I'm just looking for confirmation that I can restore *everything* in case of disaster, and which one would do that. It looks like ADB may be more complete...but I don't know.

Hey everyone,
I know there are fixes to a md5 mismatch error I can run on my file. My question is, why does EVERY backup I create has a md5 mismatch? What can cause this? I tried switching recover programs rogue, cwm, etc. Tried different SD cards and using internal storage. Nothing helps. Every backup I create gets a md5 mismatch

Even renaming something in the back up will create a mismatch. Try to leave everything exactly how it is when you make the backup. If you're already doing that, I'm not sure what to tell you.
hey, so today i rooted my galaxy note 3 (n9005) using the cfire auto method. i installed cwm recovery on the device and tried creating a nandroid backup. it all goes fine until it says backing up /data then it fails. it does NOT generate a md5 sum file. so i want to ask if the backup i have is OK to use for future restoring or should i do something else. I really dont care about my downloaded apps, when i restore, i just want a stock device.
thanks.
No, unless it generated md5 sum there won't be any file there. Where did you try saving the file, internal or external sd card?

Oh, ok. Maybe try backing up again?
First time I tried backing up mine it did it successfully even generated a md5 sum. But when I tried to restore, the md5 check failed so since then I just use an external sd card for backup.

wow, the backup was 5gb
