+# nandroid v2.2.2 - an Android backup tool for the G1 by infernix and brainaid
+# restore capability added by cyanogen
+
+# pensive modified to allow to add prefixes to backups, and to restore specific backups
+# pensive added the ability to exclude various images from the restore/backup operations, allows to preserve the newer
+# recovery image if an older backup is being restored or to preserve user data. Also, saves space by not backing up
+# partitions which change rarely.
+# pensive added compressing backups and restoring compressed backups
+# pensive added fetching system updates directly from the web into /sdcard/update.zip
+# pensive added fetching system updates directly from the web into /cache and applying it.
+# pensive added moving *update*.zip from /sdcard/download where a browser puts it to /sdcard/update.zip
+# pensive added deletion of stale backups
+# pensive added backup for ext2 partition on the sdcard to switch roms
+# pensive added composite options --save NAME and --switchto NAME to switch ROMS
+# pensive added list backup anywhere on the sdcard
+# pensive added list updates (more precisely *.zip) anywhere on the sdcard
+# Amon_RA : ext restore -> added check if ext backup is existing
+# Amon_RA : ext restore -> added check if ext parition is existing
+
+# Requirements:
+
+# - a modded android in recovery mode (JF 1.3 will work by default)
+# - adb shell as root in recovery mode if not using a pre-made recovery image
+# - busybox in recovery mode
+# - dump_image-arm-uclibc compiled and in path on phone
+# - mkyaffs2image-arm-uclibc compiled and installed in path on phone
+# - flash_image-arm-uclibc compiled and in path on phone
+# - unyaffs-arm-uclibc compiled and in path on phone
+# - for [de]compression needs gzip or bzip2, part of the busybox
+# - wget for the wireless updates

-# nandroid v2.1 - an Android backup tool for the G1 by infernix and brainaid
-
-# Requirements:
-
-# - a modded android in recovery mode (JF 1.3 will work by default)
-# - adb shell as root in recovery mode if not using a pre-made recovery image
-# - busybox in recovery mode
-# - dump_image-arm-uclibc compiled and in path on phone
-# - mkyaffs2image-arm-uclibc compiled and installed in path on phone
-
-# Reference data:
-
-# dev:    size   erasesize  name
-#mtd0: 00040000 00020000 "misc"
-#mtd1: 00500000 00020000 "recovery"

-#mtd6 is everything, dump splash1 with: dd if=/dev/mtd/mtd6ro of=/sdcard/splash1.img skip=19072 bs=2048 count=150
-
-# We don't dump misc or cache because they do not contain any useful data that we are aware of at this time.
-
-# Logical steps (v2.1):
-#
-# 0.  test for a target dir and the various tools needed, if not found then exit with error.
-# 1.  check "adb devices" for a device in recovery mode. set DEVICEID variable to the device ID. abort when not found.
-# 2.  mount system and data partitions read-only, set up adb portforward and create destdir
-# 3.  check free space on /cache, exit if less blocks than 20MB free
-# 4.  push required tools to device in /cache
-# 5   for partitions boot recovery misc:
-# 5a  get md5sum for content of current partition *on the device* (no data transfered)
-# 5b  while MD5sum comparison is incorrect (always is the first time):
-# 5b1 dump current partition to a netcat session
-# 5b2 start local netcat to dump image to current dir
-# 5b3 compare md5sums of dumped data with dump in current dir. if correct, contine, else restart the loop (6b1)
-# 6   for partitions system data:
-# 6a  get md5sum for tar of content of current partition *on the device* (no data transfered)
-# 6b  while MD5sum comparison is incorrect (always is the first time):
-# 6b1 tar current partition to a netcat session
-# 6b2 start local netcat to dump tar to current dir
-# 6b3 compare md5sums of dumped data with dump in current dir. if correct, contine, else restart the loop (6b1)
-# 6c  if i'm running as root:
-# 6c1 create a temp dir using either tempdir command or the deviceid in /tmp
-# 6c2 extract tar to tempdir
-# 6c3 invoke mkyaffs2image to create the img
-# 6c4 clean up
-# 7.  remove tools from device /cache
-# 8.  umount system and data on device
-# 9.  print success.
