Apologies for the inconvenience caused by the design change of the backup utility of Sailfish OS.
It is no more possible to save the backup data to the device storage. The available options are the memory (SD) card and cloud services (e.g. Dropbox). The reason for the change was that keeping the backup data in the device itself was not a secure way to protect the data. Should something severe have happened with the device, such that there is no access to the memory system or the memory gets corrupted, then the backup kept in the device would have been lost. At a repair service they re-flash (wipe out) the whole memory... Furthermore, backup files are often quite big, consuming the precious storage space of the device. For these reasons it is better to save the backups outside of the device. We warmly recommend you to acquire an SD card - they are not very expensive these days. A 16-gigabyte card costs about 10 euros.
Do your previous backup files, which are now not reachable, contain something valuable that you would like to restore? If not and if your device is in good shape, then delete the old backups from the device by using command "Clear backup storage" in Sailfish Utilities (see https://jolla.zendesk.com/hc/en-us/articles/203837576). This would save space on your device.
Should you have something valuable in an old backup, then there may be ways to access it using the command line.
