Learn more about the capabilities and download a free trial now! hardware and OS snapshots. Two tapes show entire usage of their 1,4TB (4,6 and 4,7GB left), and the third shows 1,2TB left, so the total usage on tape is about 3TB, while actual size on disk is 2,1TB (is the size that the job is reporting to be copied on tape) This is very inconvenient. Any idea what's going on In order to have only full backups on tapes, you should either specify "source" backup job to create full backups every day or use reversed incremental backup mode. 0x1f. Library Hardware C. Cheers! Based on the video that was posted, it looks like hardware compression will be supported by this new feature, but unless I missed it, I didn't see anything relating to encryption. Optimized compression level for very Please keep in mind the uncompressed size whenever you estimate the tape consumption for Veeam backups. The total amount we need to backup ist >470GB but is it not possible to compress the veeam files cheers Michael The first tape is full and the second has over 630GB free but Veeam still says waiting for tape. If the source job uses the said mode, indeed, and virtual full backup has taken place in accordance with the specified schedule, then, I'd say that two .

Backup copy job to Windows server 2012 deduplicated disk: whether or not to include the compression? I tried running a file to tape job on an LTO-7 (not M8) tape in the LTO-8 library, and it still uses software, which eliminates M8 as an issue. Each backup-job has 1 VM in it so Veeam shows 3 VM's as pending when the job Data Compression and Deduplication; Data Exclusion. Veeam uses deduplication across the whole backup file as well which improves how much it can compress the backups, so Veeam will be getting better overall compression than the tape drive would be able to on the same uncompressed backup data. Tape encryption . I pulled the tapes out of the library to verify, and, they were not write protected. To do so, you must assign the role of If you are copying several tapes with different retention settings, Veeam Backup & Replication will set retention policy for the target tapes to the maximum retention among the source tapes. I have a job The processing rate of 1mb/s is on both the local tape ( veeam server) and in the proxy tape server. So if my critical servers full backup job is around 1. Install the proper drivers If that does not work – check the library manual for detailed instructions The Veeam server is installed on a VM, the tape is installed on a tape server through a private lan connection running at 1Gbps. 2 days ago · To share a tape device, configure a partition of the tape library that will be used only by Veeam Backup & Replication.

Ignore the compressed size quoted on all LTO tapes/drives. Before the data is written to tape, it is suggested to compress it again to save some tape capacity. The calculations above are good just look at tape capacity now. bplancic Influencer Posts: 21 IBM has announced three LTO-9 tape drives for usage in tape library TS4500. Tape compression should be disabled for tape jobs, when backup files are already compressed at the backup repository During the backup to tape or file to tape job, the key is passed to the target side. Considering Native capacity, 1080 TB of data from the design example requires 60 tapes ingnoring End of Media To enable hardware compression or specify custom scripts that you want to run before and after the file to tape job: At the Options step of the wizard, click Advanced. /Cheers! Hi all!I stumbled across an older post from Tom Sightler here: https://forums. What is the new recommendation if we only back up image level backups? Markus We have LTO5 drives which have hardware compression enabled, the tape copy job is set to use hardware compression if available. Not a support forum! The currently implemented tape PS model will be revised seriously in the next major release. The tape library should work in the application-managed encryption mode. VM-level backups and Agent-based backups created by Veeam are compressed by default, so there will be not much value of tape compression techniques. No drive included means you need to buy a compatible tape drive as well, that unit takes half height drives so any It's a SAS connected drive. Not a support forum! (as well as hardware compression). Veeam Community discussions and solutions for: Difference between Read/Size and Transferred. I removed the old the new tape library from the media pools and added the new tape library to the media pools as described in the veeam user guide and all online tapes now assigned to the new library, whereas the offline tapes (all in one media pool assigned to the new library) still show the name of the Support case ID: 00874063 I am currently experiencing very slow processing rate during any backup to tape jobs. Disabling hardware compression can increase the performance a bit. Data Compression and Deduplication; Data Exclusion. Place deduplication storage on the primary side and use object storage or tape on the second site. The number of tape drives, cartridges, and associated floor space may be Enables the hardware compression option. Then I created a single (test) tape job with 3 backup-jobs in it. I ticked the box for hardware compression, but I don't think that's working. Veeam does not appear to recognize this and insists on having the proxy host compress the data stream before sending it to the tape host. No compression on Veeam as well. If you're telling the tapes to export after the job - you'll likely have the same issue. Veeam’s backup format is Data Compression and Deduplication; Data Exclusion. Thank you. You need to do your calculation on the uncompressed capacity. Also, there should be enough space available on medias in order to host full backups. Remember that Veeam tape backup engine is currently optimized for moving small number of large files (such as VM backup files), rather than 1. g.

Create a Tape Backup Job with the following settings: - Veeam Community discussions and solutions for: So when you copy data from there it gets rehydrated and written to tape depending on the hardware compression job setting. An example (incremental but likely the same for full backups) - I have a job that shows transferred size of 619MB, however on-disk files are 717MB - presumably due to ReFS alignment adding in zero padding. On Veeam i get the actual uncompressed size. The 3 types (VM, Agent and File Share) EOM command is returned by tape device to Veeam Tape Server during backup process and another tape will be used from the media pool. Compression is activated. In conclusion - it's not NAS what causes a slowdown, it's your ESXi <--> Backup Proxy link. All hardware was identical, only OS was changed. Once it's released, lot of previously existed issues will go away. If you're using tape there's a good chance that some of those tapes should be out of the library and probably securely rotated offsite anyway. 1 TB Actual result in disk VBK file: 2. so the storage space is only 5.

Now files is writen to tape without compression checked in veeam. So for the media pool (and drives) alone, what the notation is Defines that tape library must perform hardware compression for archives. 2TB after Veeam compressed/deduped, does this go towards the LTO Native 2. Veeam is already compressing your data and the hardware compression in the drive(s) won't get you anything more than that in reality The library you linked will work fine. . Files will be written in 1:1 ratio, however Tape Library compression can be applied. The highlighted notation above is relevant only to the tape drive and media pool and will have no effect on the job that uses the media pool. Those LTO-6 numbers (2,5:1) can work when you push “uncompressed” data to tape (try to push jpg pictures or mp3 audio to prove marketing numbers are wrong). Veeam backups un-compressed, writing to backup repo, processing rates around 250MB/s. vbk that you can currently see on tapes are expected. You can select this compression level if you want to decrease the load on the CPU of the Veeam Agent computer Sidequestion regarding this; we don't use tape ourselves, but we have ran into block-size issues in the past with regards to copy jobs. R&D Forums. For example first repository is dedup based so jobs don't use compression and minimal dedupe. I have turned off compression on the veeam backup jobs and enabled Use hardware compression if available on the veeam tape backup job. Erase-VBRTapeMedium tells me the medium is hardware protected.

Most manufacturers add the hardware compression feature to their tape drives. VBK files are configured on optimal compression level. It is important to know this to proper size the LAN bandwidth. When Veeam compression works as intended i should nearly never see speeds above 300MB/sec going towards the tape drive. Veeam-02 is a proxy, Server 2012, Poweredge R620, same HBA, Superloader 3 LTO-8. What i do see: Almost always speeds above 300MB/sec which suggests the drive is applying its own compression and Veeam compression is not working as good as it should. Portable by design. 5TB native and 3TB compressed (which no one achieves of course). Yes, the tape will be an offsite backup, however, what I neglected to add is that we also plan to offload backups daily to a remote location (we have 2 possibilities, either satellite site via WAN, or physically separate building in same complex, via fiber, hopefully the latter), using Veeam or rsync. Dima P. I am no expert, but I think that this is not optimal write speed for this configuration and in worst case it should runs around 150MB/s +- in uncompressed mode. Then it doesn’t leave many changes to tape software for further compression. Top. This allows performing data compression by a drive. If you want to have compression, utilize hardware one. 5 will appear as High in the user interface after the upgrade). whenever you store the Veeam data uncompressed (on dedup applainces) then you should enable the tape hardware compression setting as the data get´s rehydrated from dedup storage (data is uncompressed and undeduplicated then) and tape compression would reduce data in most cases more than 50%. I have two Veeam servers. hardware compression vs software compression is that hardware will put more data on the tape, A Veeam Backup file is already compressed. Before You Begin; Step 1. 1. This feeds back into Veeam tape handling being bolted on During the backup to tape or file to tape job, the key is passed to the target side. We want to backup the files created by the veeam backup - the extension of these files is vrb. Backup files are already compressed and deduplicated, so tape hardware compression does not really affect the space consumption on tape.

Veeam level 2 support helped me with this issue. Since in this case Veeam is already backing up to a compressed disk file, and this pushing this compressed file to tape, you will generally not get significant compression from the hardware so the tape capacity is more like the "native" capacity of the device which, in the case of LTO4 is 800GB (probably why Veeam displays 781GB). You can Veeam Community discussions and solutions for: LTO-8 Drives of Tape. This allows performing Hi @takayuki. Otherwise, Software compression is used automatically. My suggestion is to draw a data flow diagram with every NIC, HBA, and Switch listed and check if all ports are set to MAX speed, Jumbo Frame and use Tape/Library tools to check for drive performance. It all works fabulously. By default, Veeam will see if Tape Library supports Hardware Compression to use it. The tape drive has a hardware fault: Eject the tape or magazine. Hardware compression is already disabled but doesn't make a difference. 5TB instead of 15. backup files) only; And tapes seemed like a good idea as the price per GB was much lower compared to magnetic drives,SSD, or cloud storage, besides the initial upfront investment of the hardware.

Backup To Tape of Veeam Jan 17, 2025 · The source backup chain consists of a full backup (active or synthetic) and subsequent increments. Safest to assume that the "native capacity" (6-ish TB for LTO-7) Does Veeam use a native compression, or libraries/drives utilize hardware compression? Does Veeam offer a possibility to monitor a compression ratio in UI while I am having issues with tape compression. The changer mechanism has a hardware fault that requires reset to recover. These are typical files form a file server (many small files about 200-300 KByte). Also is there a way for me to write the backup files to tape in vmk/vmdk format so we so can restore the vm's straight from tape without Veeam somewhere down the line? Case # 01993689 and 01995686 If the tape hardware does not support encryption, Veeam falls back to using software-based AES-256 data encryption prior to sending data to the tape device (see also Tape Encryption in the User Guide).

Tape library should work in the application-managed encryption mode. In addition, try to disable hardware compression in the file to tape job properties. The SP can write backups created by a tenant in a cloud repository to a tape media. The tape library should work in the application-managed encryption Yes, with the enabled hardware compression in tape job settings. After they were reinserted into the library, what fixed them was doing an inventory on the tape. This light CPU overhead allows for excellent throughput with rates up to 150 MB/s per core and even faster decompression rates. Named. The tape drive has always been an LTO6 drive but we have only just started using LTO6 tapes - LTO5 tapes that were at a lower capacity were used previously. Defines that the existence of dependent tapes is not checked. Tape compression should be disabled for tape jobs, when backup files are already compressed at the backup repository. If tape jobs are writing already encrypted data to tape you may find it acceptable to not use tape-level encryption. foggy Veeam Software Posts: 21144 Liked this is explained right in the dashboard displayed when you click on Tape node. If you say 75%, does that mean that really more data gets copied? Or is it that the tape is not 100% full. Critical.

In theory this should tell the library to compress the uncompressed veeam full backup files but it is not working like it should. the second tape has worked as it's had some data written on to it as well. The backup was previously taken with BE, then restored and now to tape with Veeam. Veeam (at the time we started with tape) does NOT My tape drive supports hardware compression and my Veeam backups are already (software) compressed. I certainly don't have a 10GB link from the tape server to the host with the repository on it. Veeam files are already compressed so hardware compression works really hard to do nothing. Select the Use hardware compression when available check box if Veeam uses hardware encryption if it is provided by the tape device and enabled in Veeam Backup & Replication. Check if hardware compression is enabled in conjunction with Veeam compression. Rle.
