Incremental backup would auto-delete full version backup

[hiphiphip]

I setted a backup job to backup a folder about 3.4G, auto-delete was set to 30 days. But it didn't do a full backup every 30 days, all files under /var/www/files are small than 60M. There is no full version backup. I don't know how restore works but 30*60M < 3.4G I think it need to keep two full version backup to make it possible to restore to any given day within 30 days.

Could you provide the backup logs if you have them?

I tried to reproduce this problem, need to wait a few days to know the results. May be caused by my deletion. After delete backups

                    foreach ($backups as $key => $backup) {
                        if ($backup['file'] == $_REQUEST['id']) {
                            unset($backups[$key]);
                        }
                    }
                    file_put_contents($config['path'] . '/db/db-backups.json', json_encode($backups));

This would turn

[{"id":"26dd99457553d087d4330a1a931ce694","file":"cdpme-2015-10-28-18-26-21-26dd99457553d087d4330a1a931ce694.tar.gz","size":29761524,"time":1446056781},{"id":"7c27e3a5d70f3f39793eb005deb1615b","file":"cdpme-2015-10-28-18-26-39-7c27e3a5d70f3f39793eb005deb1615b.tar.gz","size":123400,"time":1446056798}]

into

{"0":{"id":"26dd99457553d087d4330a1a931ce694","file":"cdpme-2015-10-28-18-26-21-26dd99457553d087d4330a1a931ce694.tar.gz","size":29761524,"time":1446056781}}

keys was added to jason files. That's why some records are missing, and some reasons are not in order. Add

$backups = array_values($backups);

before

file_put_contents($config['path'] . '/db/db-backups.json', json_encode($backups));

could solve this issue. The same situation may also occur when dbbackupjob/acl/user was deleted.

Another two issues:

• Size of big backups is displayed as "NAN"
• IP in "Last 10 Activity Logs" shows right IP address, but IP in "Last 10 Backup Logs" shows "Not found"

I setted a increamental backup keep for 3 days, still no full version archive. There is nothing in particular in /var/log/syslog. I could set a demo server for testing.
