I have read articles suggesting the use of DropBox in conjunction with a password manager database to facilitate strong, distinct passwords that can easily be used on various computers and mobile devices; however, I've also read comments claiming that this is not safe, DropBox can't be trusted, and that doing this means you're begging to be hacked or have your identity stolen.
Assuming a TrueCrypt volume with a "strong" password/passphrase on a DropBox account also with a "strong" password/passphrase, can this solution be considered safe for online backup and synchronization of sensitive information?
By "sensitive information" I am referring to password manager databases, financial software files (like Quicken), and scans of old financial documents such as purchase receipts or even tax returns.
