Linear Tape File System is a standard format for writing files to tape. It’s ideal for storing production and post media as the LTO tapes can be mounted and read on Linux, macOS and Windows. You aren’t locked into a proprietary archive.
YoYottaID LTFS includes all the features of YoYottaID and adds the ability to create archives in parallel to two standalone LTO drives using LTFS. Quickly create industry standard archives on LTO-8, LTO-7, LTO-6 or LTO-5 tapes. YoYottaID names, formats, mounts and repairs tape archives. During the archive YoYottaID calculates MD5 checksums and uses these to verify the transfer.
YoYottaID remembers the contents of every tape created so later on you can search to find the location of shots.
LTO-5 tape holds 1.35 TB and can be read or written at 140MB/s.
LTO-6 tape holds 2.4 TB and are a little faster at 160MB/s.
LTO-7 tape holds 5.7 TB and are a lot faster at 250-300MB/s.
LTO-8 tape holds 11.4 TB and are a lot faster at 250-300MB/s.
Note that a minimum of 100GB space is reserved. So the usable space is a little smaller.
Unlike hard drives the tapes are designed with a 30 year shelf life. All tapes must have barcode labels, this identifies the tape and allows use in a library.
LTFS does allow access from the desktop, but it is not the fastest way to read and write.
Remember that LTFS is a tape that cannot be accessed in parallel.
YoYottaID has a smart queue, so multiple backups to tape can be started and they will be processed in order.
Connecting LTO drives to a Mac
The LTFS standard requires LTO-5, LTO-6, LTO-7 or LTO-8 tape drives. Drives are available with Fibre Channel, SAS, USB3 or Thunderbolt.
To connect a SAS or FC LTO-5, LTO-6, LTO-7 or LTO-8 drive to a Mac use the ATTO ExpressSAS H680 or Celerity FC PCIe cards from ATTO.
The H644 card can also be used, although it just has one external connector.
See this link for more details on the ATTO.
These PCIe cards can go inside the older MacPro or in a Thunderbolt expansion like the Sonnet Echo Express SEL shown here.
The 1 Beyond ThunderTape3 and mTape Thunderbolt units plug straight into a Mac.
ATTO Thunderlink SH1068, SH2068 TB-SAS, ThunderStream SC4808 adaptors, R680 or R644 PCIe RAID SAS cards do not support TLR, so there will be issues when using them for LTFS + LTO drives.
