Summary: Key aspects and core features of Backup & Disaster Recovery.

On this page

Infrascale Backup & Disaster Recovery allows you to:

  • automatically back up data from computers and servers;

  • restore the required versions of the backup data;

  • retain backups for unlimited time; and

  • boot DR image and VM backups as VMs running on the Cloud Failover Appliance (CFA).

Specifications of virtual Cloud Failover Appliances

Requirements for running on third-party hardware

  Requirement Notes
Supported virtualization platforms Microsoft Hyper-V 2008 R2–2016
VMware vSphere 5.0–6.7
- Nested virtualization must be enabled to support VM booting and boot verification.
- While software may run on other virtualization platforms, these are the only directly supported and tested platforms.
CPU 4 cores minimum - 4 cores is the minimum required to support 1 TB of protected data and daily incremental backups.
- Increase number of cores for larger data volumes and higher frequency of backups if average CPU load on a VM during backup exceeds 50%.
- Increase number of cores to allow boot verification and nested booting—specific to your booting needs, and as configured on the CFA for recovery booting.
RAM 16 GB minimum To manage backups and replication:
- 16 GB is the minimum required for 1 TB of protected data.
- Add 1 GB of RAM per each 1 TB of the stored data.
For example, to protect 10 TB of data, you need 25 GB of RAM.
For better performance when booting VMs on the CFA, increase RAM (in addition to minimum requirements for backup storage) commensurate with RAM needs for VMs that will boot nested (for recovery).
Backup storage 2 TB minimum (HDD or SSD) - 2 TB is the minimum required for 1 TB of protected data with daily backups and default settings for one-month retention.
- Actual storage requirements depend on the type of backup data, frequency of backups, and retention period.
- Storage for one-month retention of backup data can be calculated by formula:
1.5 × Size of DR image, VMware, and Hyper-V backup data + 1.7 × Size of file-level backup data + 2.7 × Size of Microsoft SQL and Exchange database-level backup data
See sizing examples for details.
SSD storage 64 GB minimum Regardless of the backup storage, virtual CFA requires 2 GB of SSD storage per each 1 TB of data stored on the backup storage for optimal DDFS performance.
Note: If SSD storage is used as the backup storage, this value is additional.

Note

Virtual CFA software is branded as Infrascale. A white-labeled versions are not available.

Deployment and replication configurations

CFA can automatically send data to another location. Secondary CFA is always passive, meaning it accepts the replicated data from the primary CFA, but cannot back up extra endpoints.

  Primary CFA on-premises and secondary CFA off-premises (in our cloud) Primary CFA on-premises and secondary CFA off-premises (in a public cloud) Primary CFA on-premises and secondary CFA off-premises (elsewhere other than in our or a public cloud) Standalone primary CFA
Description Data is replicated to a secondary CFA in one of our data centers in US, UK, or Canada. This is the default approach Data is replicated to a secondary CFA deployed within one of public clouds Data is replicated to a secondary CFA deployed elsewhere No replication. Data may be taken offsite by archiving to an external USB disk

Security and disk encryption

Hard disks in the primary CFAs(located on the customer’s premises) can be encrypted using LUKS,—an industry standard hard disk encryption system built into Linux.

Hard disks in the secondary CFAs(located in the Infrascale data centers) are encrypted by default using the AES-256 algorithm.

Learn more about the CFA disk encryption.

Transfer of data to the cloud is performed over AES-256-encrypted connection.

Data center security

We use Tier 3 and Tier 4 data centers. These are certified under SAS 70 Type II and SSAE 16, secured with video surveillance 24×7 and biometric access controls to limit physical access to the data center floors. All servers are security-hardened before deployment, patched, protected with antivirus software and firewalls.

For browsing and restoring, Infrascale Backup & Disaster Recovery supports ext2, ext3, ext4, XFS, Btrfs, FAT16, FAT32, NTFS, UFS, HFS, HFS+, JFS, ReiserFS, MINIX (1.0, 2.0, 3), exFAT, NILFS2, F2FS on both MBR and GPT partitions, or on software RAIDs or dynamic disks in Windows. ZFS was not tested. Windows Storage Spaces, Reiser4, and ReFS are not supported for browsing and restoring.

Virtual machines in Xen environments

Backup of a VM running on Citrix XenDesktop or XenServer can be performed with the DR backup agent installed in the VM. Boot on CFA or restore to a Xen environment of a DR image backup is not supported.

Citrix NetScaler VPX CFAs running on VMware or Hyper-V can be backed up and restored. Boot is not supported at the moment.

Backup schedules

Schedules support monthly, weekly, daily, hourly, by day of week with per-minute granularity backups.

Backup data retention

For backups of VMware and Hyper-V VMs, you can set retention to keep all backups up to 14 days, one per day up to 14 weeks, one per week up to 1 year, one per month forever.

For file and folder and DR image backups of physical machines, you can set for how long to keep full, differential, and incremental backups.

Backup retention is set separately for primary and secondary CFAs.

Monitoring and reporting

CFA sends alerts and reports via email about the following events:

  • Backup and restore: VM automatic registration report, job success or failure, lack of job progress, daily and weekly summary

  • Security audit: User login notification and daily summary

  • System: New update available and system settings were changed

  • Replication: Failure, communication failure, summary report

  • License: Communication failure, violation, license warning

In the Infrascale Dashboard, there is a backup monitoring section for all CFAs of the account with email notification and integration with ConnectWise Manage and Autotask PSA.

Integrations

Deduplication file system

We use proprietary technology called deduplication file system (DDFS). All data is split in 64K-blocks, and only one unique instance of each block is stored on disk. We calculate the number of all instances in the entire stored data per each block.

  1. Unless there is an active, previously signed support contract.  2 3 4

  2. Backup of VMware VMs with NVMe controllers is not supported.  2

  3. Hardware support may be limited if replacement parts are not commercially available. 

  4. Operation in the environments with ODX enabled was not tested. 

  5. DR image backup does not support Storage Spaces, ODX-capable devices, and software-based RAID 5 arrays.  2

  6. CFA does not support booting of VMs that run 32-bit version of Windows 10 and are set up to use UEFI 2 3

  7. Hyper-V host boot is not available.
