This is not normally an issue for backups of file servers and workstations, as the larger, more time-consuming full backups can usually run in the background for a longer period without any ill effects.
Internet bandwidth and cloud storage max ingest speeds may be more limited than the local network/disk. There’s also more communication latency involved. This is not normally an issue for backups of file servers and workstations, as the larger, more time-consuming full backups can usually run in the background for a longer period without any ill effects. After the initial full backup, incremental backups serve to reduce the backup size and reduce backup times. Data compression and deduplication help, too. But specialized applications like databases (for example, Microsoft SQL Server and Exchange) can be affected by longer backup times. You want those applications backed up during times of low activity and within your maintenance windows. In those cases, look to back up critical applications locally for best speed and then sweep up the backups to the cloud. Some cloud backup softwarewill automate this process for you.
