Notes is the built-in system application to take quick text notes. To backup or restore the data of this application without iTunes, the following information might be useful. Initial data for this analysis comes from an iPhone 3GS with firmware 3.1.3, which was later restored / upgraded to an iPhone 4 and finally to an iPhone 4S with iOS 5.0.1. On lower or higher firmware versions there might be small differences in the data.

In the folder /var/mobile/Library/Notes/ there are two files:

  • notes.sqlite
  • notes.idx

The second file is probably used for indexing and can be recreated if deleted (?). Looking at the file notes.sqlite, this is an SQLite database with the following tables in it:

Z_ENT table name name2
sqlite_master
1 ZACCOUNT Account
2 ZNEXTID NextId
3 ZNOTE Note
4 ZNOTEBODY NoteBody
5 ZNOTECHANGE NoteChange
6 ZPROPERTY Property
7 ZSTORE Store
Z_PRIMARYKEY
Z_METADATA

The name2 in this list is the value used for the hash in NSStoreModelVersionHashes in the bplist of the field Z_PLIST in the table Z_METADATA. The same name2 is used in the table Z_PRIMARYKEY, field Z_NAME.

The following indexes are defined:

index name table name field name
ZACCOUNT_ZDEFAULTSTORE_INDEX ZACCOUNT ZDEFAULTSTORE
ZNOTE_ZINTEGERID_INDEX ZNOTE ZINTEGERID
ZNOTE_ZSTORE_INDEX ZNOTE ZSTORE
ZNOTE_ZBODY_INDEX ZNOTE ZBODY
ZNOTEBODY_ZOWNER_INDEX ZNOTEBODY ZOWNER
ZNOTECHANGE_ZSTORE_INDEX ZNOTECHANGE ZSTORE
ZSTORE_ZACCOUNT_INDEX ZSTORE ZACCOUNT

Tables

sqlite_master

This table is contained in every SQLite database and contains general information about the content. It has these fields:

field name description
type either 'table' or 'index'
name name of the table or index
tbl_name same as name for table, related table name for index
rootpage integer, internal id where to find the data (?)
sql creation statement

This is the content of this table:

type name tbl_name rootpage sql

index ZSTORE_ZACCOUNT_INDEX ZSTORE 16 CREATE INDEX ZSTORE_ZACCOUNT_INDEX ON ZSTORE (ZACCOUNT)

Please note that the values for rootpage might differ in every database.

Z_PRIMARYKEY

This is used by the framework and holds an entry for every table. These are the fields in there:

field name type description
Z_ENT INTEGER PRIMARY KEY The identifier of the table
Z_NAME VARCHAR one of these values: 'Account', 'NextId', 'Note', 'NoteBody', 'NoteChange', 'Property', 'Store'
Z_SUPER INTEGER always 0
Z_MAX INTEGER highest Z_PK in the according table

Z_METADATA

This table is used by the framework and holds configuration data. There is only one record in the table.

field name type description
Z_VERSION INTEGER PRIMARY KEY value 1
Z_UUID VARCHAR(255) value 'D1694631-D07A-4223-9A61-42689DA4C76A' (?)
Z_PLIST BLOB binary plist

The bplist holds this data:

  • LastIndexTidAlreadySetUp=true
  • LocalAccountAndStoreAlreadySetUp=false
  • NSPersistenceFrameworkVersion=386
  • NSStoreModelVersionHashes=dict:
    • Account=*
    • NextId=*
    • Note=*
    • NoteBody=*
    • NoteChange=*
    • Property=*
    • Store=*
