I have a backup created by another application or an older version of CCC. Can CCC update my existing backup?

CCC always examines the files on the destination to determine if they already match those on the source. If you have a volume that is virtually identical to your source, CCC will copy only the items that are different between the two volumes.

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 or a disk image, but I don't have a bootable backup. How can I restore everything?

Product: 
ccc6

CCC makes bootable backups specifically to avoid this kind of situation. When you have a bootable backup, you simply boot from that, then restore everything to a replacement disk or the original disk. One step, minimal time, couldn't be easier. Occasionally people get into this sticky situation though -- I have a backup of everything in a disk image or in a folder on the backup volume, there's a clean installation of macOS on my replacement disk, now how do I get everything back to the way that it was before?

Frequently Asked Questions about encrypting the backup volume

Can I run a backup while I'm using my computer? If I have open files, will they be backed up?

Product: 
ccc6

Generally, yes. Performance will be affected during the backup task (especially the first one) as CCC reads the entire source volume and writes to the destination volume. If your work is "disk bound" — that is your applications are reading or writing to either the source or destination, then you'll notice a performance hit. If you're just reading email or writing a document, then you probably won't notice the performance hit.

Domande frequenti su CCC e macOS 11

Con l'annuncio di macOS Big Sur, Apple ha ritirato Mac OS X (10) e lo ha sostituito con macOS 11. Come suggerisce il cambiamento del numero, si tratta del più grande cambiamento di macOS da quando Apple ha introdotto Mac OS X circa 20 anni fa. Il sistema ora risiede in un sistema sigillato con metodo crittografico "Signed System Volume". Questo sigillo può essere applicato solo da Apple; le copie ordinarie del volume Sistema non sono avviabili senza il sigillo di Apple.

Domande frequenti su CCC e macOS Catalina

Se hai aggiornato il tuo sistema a macOS Catalina avrai notato un nuovo volume sul tuo Mac: "Macintosh HD - Dati". Questo nuovo volume è parte di un gruppo di volumi che è un nuovo concetto di macOS Catalina. Discutiamo in dettaglio i gruppi di volumi qui, ma il resto del presente articolo mira a rispondere alle domande su come CCC gestisce questa nuova struttura di volumi e cosa bisogna fare, semmai, per impostare i backup per macOS Catalina.

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

Product: 
ccc5

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 clone will still be present on your new startup disk.

La vecchia cartella di SafetyNet non viene utilizzata quando sono abilitate le istantanee nella destinazione.

Product: 
ccc5

SafetyNet è una funzione esclusiva di CCC che serve a proteggere i dati sui volumi di destinazione. Lo scenario più comune per cui questa funzione è stata creata è proteggere il contenuto di un volume erroneamente selezionato come volume di destinazione. Piuttosto che eliminare immediatamente il contenuto di quel volume, CCC mette questo contenuto in una cartella denominata "CCC. SafetyNet". Quando ti accorgi dell'errore di configurazione, puoi facilmente recuperare i file dalla cartella SafetyNet e poi correggere la configurazione del backup.

System problems can lead to a failure to install CCC's helper tool

Product: 
ccc5

Configuration files for privileged helper tools are placed in the /Library/LaunchDaemons folder on your startup disk. CCC never touches this folder directly, rather it uses the macOS "Service Management" service to install and load its helper tool configuration. If the permissions or ownership of this folder are incorrect, however, the Service Management daemon (smd) will fail to install the helper tool configuration, and this service offers no recourse, nor even a notification that something is wrong that should be corrected.
