[Q] using twrp to back up efs - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have a quick question...I have an i337m and have backed up my efs with twrp and efs pro. I am noticing a big difference in sizes. TWRP backs up sizes that are a few bytes and efs pro is just a little over 2 megs. Is this correct due to compression differences? I just want to be sure I have a reliable back up

I have a similar sized twrp backup of efs. I haven't had to use it so can't tell you for sure if it'll work but I trust twrp. Mine is 53kb.

efs is just some personal data/phone info--afaik--why 2mb
my bu is 94kb
i don't think twrp compresses

In backup, just tell it to backup the efs partition only. Twrp gives you options for the different partitions. You just check the box

This is because as of cwm 6, it saves backups as blobs. When you backup, it will only backup what is different from other backups, and keep the rest as a general backup in a blob.
This is done to save space and reduce the time it takes to backup
So I wouldn't worry, it will restore fine providing you don't delete the blobs it needs
That's my understanding of it anyway

You can change your backup format to tar and then backup. It'll skip creating blobs and backup in tar files.
UPDATE: Sorry, this isn't working for Nexus 7

The problem I have with the blob method is that CWM was using 2 GB of storage for just two backups. So I switched to TWRP but now that I know about the tar option in CWM, I'm switching back.

I reinstalled CWM (Pro) but I just cannot find anywhere to change the backup setting to tar. I looked in the app, app settings, and recovery.
Can you please provide details on how to set the backup mode to tar ?

Sorry People, I just got my Nexus 7 in hands recently. My early phone is a Galaxy R which has this option of choosing backup format as tar in CWM 6. Thought it might well be the same for Nexus 7. Sorry again for posting misleading information. Hope not to repeat again.

Nandroid File Location

Got my Nexus Thursday so rooted and flashed recovery (twrp) Friday and did a nandroid in prep to flash aosp ROM but when I went looking for the file I noticed its in /data/media/tarp/backups as opposed to /sdcard/tarp/backups. Is there a way to change the directory? I created the backups folder under the trwrp on the sdcard but the backup didn't save there where I did a 2nd nandroid as a test. Do I need to fix permissions or anything?

/sdcard is a link to /data/media. They are three same file.
Just make sure you use the latest version in TWRP as it properly handles the changes in directories introduced in 4.2.

Cool. I downloaded the image from the twrp site and installed via adb so it should be correct. I guess I can install Goo Manager and make sure its up to date. I was concerned that if I wipe /data before a restore that I'll delete the nandroid.

Note that in TWRP a factory reset will format /data EXCLUDING /data/media. This means it won't wipe your /sdcard.

Titanium Backup.
Restoring the data partition could cause ROM problems, like FCs, and stuff that doesn't worn properly.

Twrp Backup system vs system image

I just went to backup my stock ROM and noticed that twrp now lists system and system image. What is the difference between the two / do both need to be backed up and restored. Also what is contained in the vendor partitions.
Thanks

how to take backup of efs using twrp

How can i take backup of my efs using twrp ? Is that possible ?
You can but not sure if it will be a full EFS backup. If You mess up Your IMEI You can use factory binary to fix it.
