Yes, volumes can be increased at any time and as often as you want.
If the volume is formatted with file system, it can simply be extended after the increase.
Block Storage is currently available at Data Center IT3.
Volumes can be transferred from one location to another by exporting and subsequently importing the data.
Both cases involve making a copy of data to be able to recover it at a later date.
Unlike a Snapshot, backup is usually archived on a different platform from the one housing the original data and in a separate location to offer greater security. Snapshot, on the other hand, uses the same storage platform and shares the same location.
The maximum size currently allowed per volume is 16 TB. We recommend, however, creating multiple smaller volumes, whenever possible.
The disks used by the Block Storage service are SSD disks with NVMe interface and are able to deliver up to 1,000,000 IOPS.
Volume performance can obviously vary according to specific use cases and also based on the size of the blocks.
