ggirao Posted April 19, 2013 Report Share Posted April 19, 2013 Hi there, I need to change my backup/storage solution. We are using Tandberg with LTO3/4 tapes for daily backups. I'm considering changing to NAS daily & weekly LTO. What do you suggest? TY Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted April 19, 2013 Report Share Posted April 19, 2013 Restoring from a disk media set is MUCH faster than restoring from tape. The files may be spread over numerous tapes. And even if you use only one tape, it may take a lot of time positioning the tape to read just one file. As long as the NAS and the Retrospect server is on the same gigabit ethernet, that should be fine. You schedule daily backups with the disk media set as the destination. Then you schedule a "Copy backup" script that copies from the disk media set to the tape media set. Select "Copy the most recent..." Quote Link to comment Share on other sites More sharing options...
ggirao Posted April 19, 2013 Author Report Share Posted April 19, 2013 As I said before: You are the man! My LTO Tape drive/Library is under maintenance. That's the next step :-) Quote Link to comment Share on other sites More sharing options...
ggirao Posted April 19, 2013 Author Report Share Posted April 19, 2013 And any good NAS (and cheap/reliable) solution? Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted April 20, 2013 Report Share Posted April 20, 2013 Does it have to be a NAS? Can it be a local drive? What kind of connections does your Retrospect server have? Thunderbolt? USB 3? Firewire 800? How much data are we talking about? (How much is stored on your tapes now? Then double that amount for the minimum size of your storage.) "Reliable" means a RAID-5 system, preferable with four drives. While those are cheaper than systems with six or eight drives, they are not "cheap" and they are more expensive than single or dual drive storage. So you must decide what you want: Reliable OR cheap?

ggirao Posted April 20, 2013 Author Report Share Posted April 20, 2013 so, im considering several solutions: - 1 Big NAS (yes with Raid5 minimum 5 drives) - Synology/Lacie/Promise - If Local: . Now we are using FC (Tandberg is 2Gbps) and disk are 4Gbps . I'm thinking if we can install retro on a new server that supports Thunderbolt (Dont want USB nor FW800) and backup from here, but all other disks to backup are LAN Gigabit connected, so... In my accounts we are using about 15-20TB Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted April 21, 2013 Report Share Posted April 21, 2013 With 15-20 TB of data you should use local storage. Either thunderbolt or Fibre Channel. Quote Link to comment Share on other sites More sharing options...
ggirao Posted April 22, 2013 Author Report Share Posted April 22, 2013 Ok. I'm considering using a M Converter from FC (from the server) to thunderbolt (to the disks). I just saw this: http://www.promisewo...com/SANLink.asp but i'm not sure if it does opposite way. TY Quote Link to comment Share on other sites More sharing options...
Proficient Posted April 23, 2013 Report Share Posted April 23, 2013 I like RDX... Disk-based storage with removable cartridges for keeping backup sets off-site. Quote Link to comment Share on other sites More sharing options...
