Leo Koppelkamm 2e6c410336 Make backups more configurable
Backup location and maximum age can now be configured in the admin panel.
For now only S3 is supported, but adding other duplicity supported backends should be straightforward.

Joshua Tauberer febfa72d60 race condition between backups and status checks - connection refused
At the end of the backup, wait a bit for dovecot and postfix to finish restarting.

Hopefully fixes #381.

Joshua Tauberer 36168b4609 add a 'backup --verify' command to run duplicity's verify command to check that the backup files are OK 2015-04-11 18:43:46 +00:00
Joshua Tauberer d8279c48ac new backup method tweaks
* use the AES256 cipher, be explicit that only the first line of secret_key.txt is used, and sanity check that the passphrase is long enough
* change overship of the encrypted files to the user-data user
* simplify variable names in management/backup.py
* although I appreciate long comments I am trimming the commentary about the backup migration
* revise the control panel template to not refer to the old unencrypted files
* add CHANGELOG entry

David Piggott 4232245546 Use built in duplicity encryption (GPG) for backups, closes #362, closes #363
[Josh merged some subsequent commits:]

* Guard via idempotency against termination between migration operations
* Final corrections and tweaks
* Pass passphrase through to all duplicity calls

Empirical evidence (a failed cron job) shows that cleanup requires the
passphrase (so it presumably needs to decrypt metadata), and though
remove-older-than has been working fine without it, it won't do any harm
to set it in case that changes or there are any special cases.

* Add back the archive-dir override but locate it at STORAGE_ROOT/backup/cache

Joshua Tauberer 1312b0254b backup: dont remove old increments because then we lose the backup history right before the last full backup, instead let them disappear along with full backups when a whole chain becomes very old 2014-08-11 11:45:40 +00:00

Joshua Tauberer 8bd62aa3bc increase duplicity's volume size from the default of 25MB to 100MB so we create fewer files 2014-06-09 13:47:41 +00:00
Joshua Tauberer 5490142df5 re-do the backup script to use the duplicity program
Duplicity will manage the process of creating incremental backups for us.
Although duplicity can both encrypt & copy files to a remote host, I really
don't like PGP and so I don't want to use that.

Instead, we'll back up to a local directory unencrypted, then manually
encrypt the full & incremental backup files. Synchronizing the encrypted
backup directory to a remote host is a TODO.
