1. How can I make sure that CFI/bootstrap i backed up to DD after each group/save set backup? What is the best practice?
NetWorker will automatically do index backup after every client backup for that particular client and it will save to same pool,if you have not configured the seperate pool for index or bootstrap backup.
2. If I configure scheduled cloning of data residing on DD to Scalar i40, will Networker automaticaly choose next available tape and change the tape if it is full or I have to prepare media manually?
Yes, Networker will automatically choose next available tape if it is full. To achieve that you need to enable the auto media management on the Library.You can also use the recyclable media from other pools, for that you need to enable 2 options on the pool properties 1) Recycle to other pools 2)Recycle from other pools
3. How is retention kept on i40 tapes? When data expires, will Networker automaticaly use the tape with part of recyclable free space or it will wait when all data on the tape expires?
Tapes retention will be determine by the client retentions.Tape will expire and set to recyclable, when all the saveset within that tape expires and untill then networker will not use that tape to save other data.
4. If all hosts are VMs, does it make sense to use BMR or it's better just to recover whole VM image through VBA?
Please let us know are you doing image level backup or Guest based backup for those VM.
5. Does anyone know when 8.1 will be supported with Scalar i40 (currently ony 8.0 is officialy supported)? I asked Quantum, but no answer arrived :-( It seems to be working but the customer requires a paper.
Please refer the NetWorker Hardware compatibilty Guide.
- The bootstrap is actually created when the Networker server's client ist backed up. This is usually once a day as a group normally runs once a day. However, if this client is not a member of an active (enabled) group, NW will generate a bootstrap backup with every group (as it does not know when the next opportunity will appear).
- It is the nature of an autochanger/autoloader control program to do all media movement automatically. However, you need to prepare (label) foreign/unknown/unused tapes. NetWorker can even do that by activating Auto Media Management (AMM), a jukebox option.
- Once the media is full (which is already etected by the device), a backup software cannot continue and will autochange the tape with another one with the state 'appendable' (it must not necessarily be empty) from the same pool. If there is a tape that he can overwrite (state: recyclable) he will do that according to the other parameters like 'Recycle from other pools'.
- Once all save sets an a tape have expired the media becomes 'recyclable' - if you want to browse through the save sets it appears to be empty. However, NetWorker will delete the save setsNOT relabel a tape just because it has expired. There are 2 reasons:
- NW will keep the data to maximize data protection.
- If such tape is relabeled, it will become 'appendable'. Therefore NW is not allowed to recycle it automatically if it is needed by another pool (assuming the recycle parameters are correct).
- Do not forget that save set expiration works independently from the tape fullness state - a tape must not necessarily be full to start/end save set expiration.
- Here is the link to the Hardware Compatibility Guide: "System Error" (hover over this area). As a jukebox interface uses 98% ;-) standard SCSI commands, there is usually no compatibility issue once it has been 'tested, approved and supported' for one NW relaease. This is what the HW Compatibility Guide lists. So even if your model is not listed (any longer) in the doc, this does not mean that it will not run. Just the configuration might be a bit more complicated.
