garyd9 originally ported ClockworkMod Recovery 5.0.0.x to the Tab 7 Plus (all variants) in late 2011. Gary's since moved on to bigger and better things, and so has ClockworkMod Recovery. As of ClockworkMod Recovery version 6.0.0.x backups and restores should be faster, take up less space (due to file-level deduplication), and there's a swanky new look (though a bit iOS-y).
wtf is "recovery" anyways?
Recovery mode is a minimal, alternative mode of booting which allows you to install software from zip files, backup/restore your device, and perform low-level operations like factory reset and formatting partitions. All Android devices have a recovery mode (it's part of the stock AOSP environment), but the default recovery mode is very limited. For example, it only allows you to flash zips which have been signed by the vendor's private key.
ClockworkMod Recovery was developed by Koushik Dutta (@koush), and is much more flexible... If you want to flash CyanogenMod, you MUST have a non-stock recovery. Right now that means ClockworkMod Recovery.

Flashing with Heimdall
I recommend flashing with Heimdall; it's open source and cross platform, whereas Odin is a leaked internal tool from Samsung, and only works on Windows. I absolutely cannot give guidance on using Odin. As of this time I recommend using Heimdall 1.3.1 (1.3.2 has a known bug which prevents flashing some files from completing successfully).
You can use the GUI (heimdall-frontend), or flash from the command line. In Linux it's easy:
- Unplug your tablet from USB
- Turn your tablet off
- Hold Volume Down and press the power button, keep holding Volume Down for 5 seconds
- Plug your tablet back into the computer
sudo heimdall flash --recovery p6200-clockworkmod-184.108.40.206.img
After that you should now have ClockworkMod Recovery installed.
Booting into CWM
There are a few ways to get into ClockworkMod Recovery:
- Using adb, type: adb reboot recovery
- From CyanogenMod's power menu: hold down the Power button for a few seconds, then navigate to Reboot -> Recovery.
- With the tablet off, hold Volume Up and press power, keep holding Volume Up for 5 seconds
I've tested backing up and restoring to CM9 and stock a few times, and it seems to work well. But please back up your stuff with other applications, like Go Backup or Titanium Backup just in case something goes wrong with restoring.
