How to set passphrase on Windows (Windows credential storage cleared unexpected)

Today I found Duplicati couldn’t work again - this issue just happened last month, today I just found this issue caused by CCleaner, I used it yesterday, and it cleared all credentials in windows credential storage.

I have try (******** indicates passphrase)

Duplicati.CommandLine --passphrase ********
Duplicati.CommandLine --passphrase = ********
Duplicati.CommandLine --passphrase:********
Duplicati.CommandLine --passphrase=********
Duplicati.CommandLine --passphrase = ‘********’
Duplicati.CommandLine --passphrase ‘********’

I wonder what format is right.

I reconfigue all backup in WebUI (using previous passphrase and backup destination, so it needn’t start backup from scratch). Maybe this is ths easist way.

Ouch! Duplicati also stores the database encryption password in there. If you wipe that, Duplicati cannot read the configuration database.

You can use either:

Duplicati.CommandLine --passphrase=******
Duplicati.CommandLine --passphrase ******
Duplicati.CommandLine --passphrase="******"
Duplicati.CommandLine --passphrase "******"

Thank you for your reply. I just found I login via systray, so I haven’t set passphrase (not used for encrypt backup file) manually, hence in this situation, automatically export backup configuration (to remote, like WebDAV storage) is a better solution.
