Storage

Backup, Backup, Backup!

Hard drives, SSD’s, Flash Drives, SD Cards, and computers do fail without warning. Make sure you regularly backup your data, photos, videos, etc.

  1. Data should exist in a minimum of three devices/places. The 3-2-1 backup strategy means you have a total of three copies of your files. Two of which are local, but on different devices/drives. And one additional copy offsite.
  2. One of the places should be off-site.
  3. Your off-site backup should not be live synced.
  4. Test your backup procedures and medium to make sure,
    1. You’re backing up what you expected.
    2. You can successfully restore from the backup.
  5. RAID is not a backup.

File Synchronizing, Copy & Backup

  • FreeFileSync is a folder comparison and synchronization software that creates and manages backup copies of all your important files. Instead of copying every file every time, FreeFileSync determines the differences between a source and a target folder and transfers only the minimum amount of data needed.
    • Tip: User Synchronizing: Mirror mode if you’re just backing up, and not changing anything on the destination needing to sync back to the source.
  • TeraCopy – Streamline your file management tasks by enhancing file copy and move functions. TeraCopy can verify files after they have been copied to ensure they are identical.
  • Syncthing is a free, open-source peer-to-peer file synchronization application available for Windows, macOS, Linux, Android, Solaris, Darwin, and BSD. It can sync files between devices on a local network, or between remote devices over the Internet. Data security and data safety are built into its design.
  • ShotPut Pro – The industry standard for offloading video, audio and photo files. Make multiple, verified copies from one source.
  • OffShoot allows you to create multiple copies, backups, and archives from multiple sources simultaneously. Built with video workflows in mind, OffShoot performs verified transfers using checksums to/from any type of storage medium.
  • Allway Sync uses algorithms to synchronize your data between desktop PCs, laptops, USB drives, remote FTP/SFTP and WebDAV servers, various online data storage, and more.

  • TestDisk is powerful free data recovery software. It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software: certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.
  • DMDE is a powerful tool for data searching, editing, and recovery on disks. It may recover directory structure and files in some complicated cases through the use of special algorithms when other software can’t help.
  • AOMEI Partition Assistant Standard (Freeware). Works with Windows 10 full drive encryption.

Hard Drive Reliability

Windows Storage Spaces

Storage Spaces helps protect your data from drive failures and extend storage over time as you add drives to your PC. You can use Storage Spaces to group two or more drives together in a storage pool and then use capacity from that pool to create virtual drives called storage spaces. These storage spaces typically store two copies of your data so if one of your drives fails, you still have an intact copy of your data. If you run low on capacity, just add more drives to the storage pool.

  • You can use Storage Spaces to mirror two external drives. (RAID 1)

Resilient File System (ReFS)

When a mirror space is formatted with the Resilient File System (ReFS), Windows will automatically maintain your data integrity, which makes your files even more resilient to drive failure.

  • Note: ReFS in only available in Windows 10/11 Workstation, Server, and Enterprise. ReFS creation is no longer supported on standard Windows 10/11 Pro. This is why ReFS is not listed when you’re setting up Storage Spaces, or when formatting a drive.

NAS (Network Attached Storage)

A NAS (Network Attached Storage) system is a data storage device connected to a network that allows storage and retrieval of data from a centralized location for authorized network.

Best Practices

  • Use RAID Level 6 or ZFS as the file system on NAS/SAN devices.
  • Do not use RAID 5, if RAID 6 or ZFS is available!
  • Try and get drives from different batches/lots, by not purchasing all the hard drives from the same vendor at the same time. Why? If a drive in the NAS fails, and is replaced, the NAS has to rebuild the RAID volume. The added stress of rebuilding may cause another drive to fail, thus, there may be insufficient data on the remaining drives to complete the rebuild of the replaced drive. Drives purchased at the same time, are probably from the same batch, and would’ve been in service for the same length of time. When a drive fails, what are the chances another from the same batch may also fail?

NAS Hardware

SATA Expansion Cards

To add additional SATA ports, use a Serial Attached SCSI (SAS) Host Bus Adapter (HBA). Instead of SATA ports, these cards have SAS ports, to which you connect four SATA drives per port. A SAS HBA with only two SAS ports will allow you to hook up eight SATA hard drives using Mini SAS to SATA Breakout Cables (x2).

Certain cards will work out of the box, such as the LSI SAS 9300-8i HBA (SAS3008) and LSI SAS 9201-8i HBA (SAS2008). Other cards will have to be flashed with an alternative firmware to enable IT-mode. That way, the hard drives connected to the card will appear in Unraid as individual disks and the hardware RAID that an HBA supports, will be completely disabled.

NAS Operating Systems

TrueNAS (formerly FreeNAS)

TrueNAS is an operating system, based on FreeBSD, that can be installed on virtually any hardware platform to share data over a network.

  • TrueNAS combines RAID redundancy, ZFS, Replication, Snapshots, Automatic Corruption Repair, and optional High Availability.
  • ZFS Primer
  • It is highly recommend you use ECC RAM with “mission-critical” ZFS with TrueNAS.
    • Systems with ECC RAM will correct single bit errors on the fly, and will halt the system before they can do any damage to the array if multiple bit errors are detected.
    • The ZFS filesystem (which TrueNAS uses) requires 1GB of ECC RAM for every Terabyte of storage.

SnapRAID is a backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures.

Decentralized Storage

“We put a lot of trust in cloud storage providers, presuming that they’ll keep our data safe. But what if they’re hacked? Or their servers go down? Or what if they decide to just kick us out of our accounts, and we lose all our emails, files, contacts, photos…” NBTV

Long-term Archival Storage

Standard writable optical media, CDs & DVDs, etc., are not reliable for long term storage. The die used with optical media degrade with exposure to light, temperature extremes, moisture, etc. Because of this, you may not be able read parts or whole files/data from the media within several months to 5 years.

M-DISC (Millennial Disc) by Millenniata, now Verbatim, is the standard for digital archival storage. Unlike traditional optical media, which utilize dyes that can break down over time, data stored on an M DISC is engraved on a patented inorganic write layer – it will not fade or deteriorate. This unique engraving process renders these archival grade discs practically impervious to environmental exposure, including light, temperature and humidity.

  • M-DISC optical media are readable in conventional optical drives.
  • ISO/IEC 16963 standard longevity tests have proven the durability of M DISC technology, and it withstood rigorous testing by the US Department of Defense. Based on ISO/IEC 16963 testing, M DISC media has a projected lifetime of several hundred years.

Microsoft Windows and Office ISO Download Tool

  • Use the Microsoft Windows and Office ISO Download Tool to download ISO’s directly from Microsoft’s servers.
  • The Windows 10 ISO gotten from with this tool is better than the one created via Microsoft’s Media Creation Tool, as it includes “install.wim” which can be used to deploy Windows 10.

Rufus

  • Create bootable USB drives from ISO images of CD/DVD discs.
  • Can be used to create a live bootable “Windows to Go” USB Flash Drive on Windows 10 Professional.
  • FreeDOS is built in. Nothing else needed to create a bootable FreeDOS USB Flash Drive.
  • UEFI: When using GPT UEFI:NTFS format/bootloader, to boot from the media, you must disable disable Secure Boot.

YUMI (Your Universal Multiboot Integrator)

  • It can be used to create a Multiboot USB Flash Drive containing multiple operating systems, antivirus utilities, disc cloning, diagnostic tools, and more.
  • Contrary to MultiBootISOs which used grub to boot ISO files directly from USB, YUMI uses syslinux to boot extracted distributions stored on the USB device.

XBoot

  • An easy-to-use utility for creating Multiboot USB/ISO.
  • You may have seen many bootable ISO files like Linux live CDs , Antivirus rescue CDs etc. XBoot can combine these ISO files in to one Multiboot ISO file or create Multiboot USB in just few clicks.
