Is it possible to run only differential backup manually?
Sorry, but there is no way to do it. Only Full backups can be performed by clicking the “Run Now” button.
Hi, this would be a feature we are also interested in: Sometimes it happens that a differential or trx backup failed and we would like to re-run it to see if the problem persists or just because we need an additional ‘quick’ backup instead of the ‘full’ one.
Thank you for the details.
If your differential or transaction log backup failed, then we recommend you to perform a full backup, otherwise, your backup chain can be broken and you’ll not be able to restore your backups. Please find more details at https://sqlbak.com/academy/backup-chain
