Can I run backup tasks while my system is on battery power?

Product:

CCC can run backup tasks while the system is running on battery power, but will not (by default) start automated tasks when your laptop is running on battery power. Backup tasks generate a lot of disk read and write activity, and that can run your battery down. Additionally, macOS tends to aggressively put the system to sleep when it's on battery power, causing task completion to be deferred until the system is awoken.

Identificar y resolver problemas de hardware

Hay varios patrones de comportamiento que inevitablemente se reducen a un problema con un componente de hardware entre el Mac y el almacenamiento. Siempre que observe errores aleatorios, cualgues, cierres erróneos, que el volumen de destino «desaparezca» en plena tarea de copia de seguridad, avisos del Finder de que un disco se ha expulsado incorrectamente, bloqueos del Finder y demás comportamientos irregulares, tenemos que recurrir a la resolución de problemas de toda la vida para descartar un componente problemático.

¿Por qué algunas aplicaciones se comportan de modo distinto o piden el número de serie al restaurarlas desde la copia de seguridad?

Product: 
ccc6

Algunas aplicaciones no funcionarán al transferirlas a otro disco o al ejecutarlas en otro Mac. Esto no tiene nada que ver con que CCC realice una copia de seguridad de sus datos, o de qué modo la realiza, sino con los requisitos de serialización impuestos por el fabricante del software (esto es, su estrategia antipiratería).

¿Por qué la cantidad de espacio usado en el disco de copia de seguridad no coincide con la del disco de origen?

Product: 
ccc6

El uso del disco en su disco de arranque no refleja el volumen de datos objeto de la copia de seguridad. El uso del disco en el destino debe ser inferior al uso del disco en el origen después de realizar una copia inicial de su disco de arranque. Los dispositivos con sistemas de archivos especiales (por ejemplo, instantáneas de sistemas de archivos) y algunos datos de servicio de macOS no pueden o no deben copiarse en otro volumen. CCC excluye automáticamente estos elementos para evitar problemas al arrancar desde la copia de seguridad y evitar un uso del disco innecesario.

Why does CCC say that my Mac is booted from a backup volume?

Product: 
ccc6

If you boot your Mac from a backup volume, CCC will be started upon login to ask whether you'd like help restoring from that backup volume. Sometimes, though, this offer is made when you're booted from a production volume, not a backup. CCC makes this assessment based on your currently-defined backup tasks. If you used CCC to migrate from one drive to another, then the task that you used to perform that backup will still be present on your new startup disk.

When I boot from my backup, Little Snitch reports that its rules have been replaced by a different version. Why, and how can I avoid this?

Product:

According to ObDev developers, it is crucial for Little Snitch to avoid unnoticed ruleset changes. Little Snitch therefore has numerous mechanisms to detect whether it is using the exact same ruleset file, as in, on the same volume and at the same physical address on that disk. This sort of mechanism makes it impossible for Little Snitch to use the ruleset on the booted backup volume without physical intervention from a user at the system (thus the dialog asking if it's OK to use the current version of rules or to use a default ruleset).

Frequently asked questions about the CCC SafetyNet folder

Note: The topics in this article are not relevant to APFS-formatted destination volumes that have CCC snapshot support enabled. For those volumes, CCC leverages snapshots to implement the SafetyNet functionality, and the snapshots aren't affected by any of the shortcomings described here.

I have a full-volume backup in a folder, but it's not accepted by Migration Assistant. How can I restore everything?

Product: 
ccc6

When you configure CCC to back up your startup disk directly to a locally-attached backup volume, that backup is automatically compatible with Migration Assistant. Occasionally people get into this sticky situation though -- "I have a backup of everything in a folder on the backup volume, I have a clean installation of macOS, now how do I get everything back to the way that it was before?"

This situation requires an intermediary restore to a new, empty volume.

Can I use CCC to copy a Time Machine backup?

Product: 
ccc6

No. Copying a Time Machine backup volume with anything other than the Finder is not supported (by us, nor Apple); CCC specifically disallows copying anything to or from a Time Machine backup volume. Apple does not document a procedure for making copies of Time Machine volumes.
