Undark - a SQLite deleted and corrupted data recovery tool
Please note if you're wanting to recover deleted data: if the database has already been fully vacuumed and defragmented, then the likelyhood of any useful data being recoverable is minimal. Undark relies on the principle that most databases do not actually purge the data from their files when you delete, at least until they're vacuumed.
Undark is a tool that will go through your entire SQLite database file and dump out all rows of data it finds still intact ( both current and deleted rows ). Undark does not differentiate between current and deleted data. The output of Undark is plain text CSV format.
Now available at GitHub ( https://github.com/inflex/undark )
What Undark can do:
- Retrieve most available records from a SQLite3 DB and dump them to stdout
- Dump normal (visible) records to stdout
- Dump deleted (unvacuumed) records to stdout
- Retrieve data from corrupted SQLite DBs (because it only examines data on a per record basis)
- Recover data that's already been vacuumed out of the file
- Magically put the records back in to your db file
undark -i <sqlite DB> [-d] [-v] [-V|--version]

[--rowsize-min=<bytes>] [--rowsize-max=<bytes>]
[--no-blobs] [--blob-size-limit=<bytes>]
[--fine-search]
-i: input SQLite3 format database
-d: enable debugging output (very large dumps)
-v: enable verbose output
-V|--version: show version of software
-h|--help: show this help
--cellcount-min: define the minimum number of cells a row must have to be extracted
--cellcount-max: define the maximum number of cells a row must have to be extracted
--rowsize-min: define the minimum number of bytes a row must have to be extracted
--rowsize-max: define the maximum number of bytes a row must have to be extracted
--no-blobs: disable the dumping of blob data
--blob-size-limit: all blobs larger than this size are dumped to .blob files
--fine-search: search DB shifting one byte at a time, rather than records
Example usage:
./undark -i sms.db > sms-data.csv
