Is Image Snapshot Different from Backup Snapshot?
If an image size is limited to 2GB and a Linode disk size may be say 30-40GB, which 2GB are selected for the image? How can a 2GB image be used to "clone" a new Linode if most of the files are not included? Are just the system files saved, e.g., not including /usr/local/ or /home/ files?
Unable to create image. Size of disk (4141MB) is larger than the per-image limit of 2048MB.
(my disk was 20000MB)
You would need to make sure that there really are 2GB or less of that disk space being used before being able to make an image of that disk.
If it was successful you'll have the disk exactly as it was when the image was created, files and all.
