What is block level backup? There are two equally likely meanings of this term, both always opposed to file-level backup:
- Many sources use “block-level backup” to refer to hard disk snapshots, i.e. backups created by sector-by-sector copying of physical HDD contents without querying file system.
- Others use it as a synonym of differential backup which is an optimization technique that lets you reduce storage space required to store multiple backup versions by computing and backing up byte-level differences between them.
Whatever you are looking for, our block-level backup software supports both!
Block-Level Backup VS File-Level
As compared to “common” file-level backup, block-level backup method has its own pros and cons:
- Data backed up. Working with hard disks on block level lets you access boot sector, master file table, system files and other data that can’t be copied via file system queries. It means that block-level backup is the only way to create system backups.
- Granularity. Block-level backup doesn’t provide much flexibility. Unlike file system-based copying that lets you protect individual files and folders, it can back up complete disk images or partitions only.
- Size. Since the smallest logical object you can back up on block level is an HDD partition, you need to make sure that you have enough disk space to store the data.
- Speed. Generally, copying data on block level is faster than on file level. However, it is true only for equal amount of information. If your partition has only one file, common copying will take less time than making a complete drive snapshot.
