I have put the USB Drive into my Sony Xperia Z2 and used the App and I am doing a backup of my internal Sandisk 64GB Micro SD 64GB Card. How do I know when the backup is complete? It has been in there for an hour and nothing seems to be happening. It just said when I started the backup, that it would perform operation in the background.
Hi Upweyguy ,
_ Dear member of SanDisk Community, welcome. _
Please, test on laptop, to microSDXC 64 GB, in the port-card directly, with a quality adapter (not a generic), and see what happens.
Luck, and then you tell us, what happened, please.
Regards, Alfred. (Google translated)
From what I know, there should be a confirmation message that it’s complete. But how did this worked for you sof far? x
ehh? (…and 7 days later…)
So far I have not been able to complete a backup without a fail message. I have re-formatted the device again using exfat and I’ll see how I go.
If the device is formated at FAT32 the maximum file size it can hold is 4 GB. If your backup is larger than that you do indeed need to reformat it to a different format. I would have suggested NTFS but exFAT should work for you also.
