Snapshots

Data backup and recovery times are extremely important to both home and business users. A survey

of 300 enterprise and small-medium businesses in Taiwan (“Taiwan IThome survey 2017＂) found

the following:

- 60% of businesses used remote replication for backups.

- 50% of businesses expected data recovery to take less than 1 hour.

- 50% of businesses experienced data recovery times of more than 1 day.

Snapshots help to reduce backup and recovery times. Instead of copying data to another location,

snapshots freeze data blocks in a volume or LUN, preventing them from being modiﬁed. When a

volume or LUN needs to be recovered, the system can mount the unmodiﬁed data blocks directly.

Restoring all data in a volume using snapshots is up to 10 times faster than restoring the data by

copying it from a backup source.

Snapshots are also a differential backup solution. This means that they only use additional

space when data is modified. The frequency of backups can be increased while reducing space

requirements.

QNAP has developed its own proprietary ext4-based snapshot technology in QTS that reduces

RTO (Recovery Time Objective) and RPO (Recovery Point Objective). QNAP snapshots have several

advantages over the open-source Btrfs snapshot technology used by competitors.

Ext4 is Fast

Ext4 has less I/O latency than Btrfs. In the same test environment, ﬁle transfers using Samba on an

ext4-based QNAP NAS were 61.5% faster than another brand's Btrfs-based NAS. Benchmark tests

from Phoronix, a leading website for Linux hardware reviews, show similar results.

Block-Based Snapshots Protect Your Data Against Ransomware

Ransomware is a type of malware that denies you access to your data until you pay the creators.

Ransomware attacks, such as the high-profile WannaCry outbreak, can affect both home users

and businesses. QTS block-based snapshots store their data at the block-level, which file-level

ransomware cannot access or modify.

Data and Snapshots are Stored Separately

QTS stores snapshots outside of the volume, in unallocated storage pool space. This enables you

to better utilize the free space on your NAS, and prevents snapshots ﬁlling up all the space on a

volume. On Btrfs-based NAS devices, snapshots are stored in the volume and occupy the same

space as user data.
