"Insert next volume" message when backing up to a USB flash drive
Acronis True Image Home treats your USB flash drive as removable media. If it is formatted in FAT32,
the size of one file is limited to 4GB, so when your backup exceeds this size the program
automatically splits it into 4GB volumes and waits for insertion of the next media for the next volume.
Just click OK and the backup process will continue. Repeat this if the message is displayed again until
your backup finishes. For more detailed information see the Acronis Support KB article "Acronis True
Image Asks to Insert Next Volume When Backing Up to USB Flash Drive" at
http://kb.acronis.com/content/1805.
