I wanted to know what the best practices are for backing up and restoring a SQLite DB on android. Currently I approach the issue by taking the DB to be backed up and using File Input/Output Streams to copy it to the sd card. Then I use the reverse process if I want to restore and old backup.
This method seems to work and has not yet corrupted my data. I am wondering if this is the best approach or if there is a safer way of doing this?
Thanks
This seems like it would be the best approach. You may want to consider taking a checksum of the SQLite file before copying and comparing it with the destination file for extra assurance. Just ensure there are no open connections to the database when you take the copy, otherwise you may end up with the DB in an unexpected state when it’s restored.
The only other way I could see to do it, would be to read the actual contents of the DB and generate a file containing the SQL which which it can be restored from, this is obviously a more complex and doesn’t offer any advantages to justify this complexity.
