Android Backup Keeps cancelling

Hi Guys

im Trying to backup my android phone to Sandisk Ultra Dual Drive.

the Backup starts normally and copies when i leave it and return later to see if its completed it just says the backup was cancelled, tried it a few times now and same every time.

Any ideas ?

How big is the SanDisk drive?  How much free space is on the SanDisk drive?  What format is the SanDisk drive?

SanDisk Ultra 256 GB Dual USB Flash Drive USB 3.0 Type-C

147 Gig space free

Format - MS-DOS (FAT32)

back up size is 2.75 gig

Hopefully you mean the format is exFAT.  FAT32 only supports drives up to 32GB.  You’re other specs look fine.

no it just says MS-DOS (FAT32)
