Backup Repositories with Rotated Drives

[baber]

in veeam document say :

Backup Repositories with Rotated Drives can be helpful if you want to store backups on several external hard drives (for example, USB or eSATA) and plan to regularly swap these drives between different locations.

i could not understand means clearly

can you give an example????

can anyone help me about this feature?????

i have read document but clearly could not understand

Rotated drives scenario, in its simplest implementation, allows to backup to one drive during the entire week, then to another one during the entire next week, while taking the first drive to another location (home or another office) for the duration of that week (think offsite backup) and bringing it back to continue backing up to it during the third week, while the second disk is taken offsite, in its turn.

i understand this :

if we select rotate drive , in same time can get backup on 2 repository : 1- default repository 2-external repository
will it work such as raid1 disks will be save one copy from all of data on the other disk ??

BR

No, your understanding is not correct. In this scenario you're backing up to a single repository at any moment in time, but rotate the drives periodically.

[baber]

excuse me i understand your means you say we can get backup on a storage and if enable rotate drive can dis join storage and another join the storage i realy confused what is benefit ????

With Veeam we recommend a 3-2-1 backup policy, where you have 3 copies of the data on 2 different types of media with one off site. A rotated media allows you to remove a physical repository drive and store it off-site. This could take many forms but to give you an example, you may be backing up to a usb hard drive, this device could be removed from the environment every night and replaced by a second device, these drives could be rotated every day to ensure that at least one copy of the backup was kept offsite at anytime. The Rotated Drive setting ensures the repository server expects the replacement of these drives and accommodates for the missing backup files.

Hi, the rotating discs can be assimilated to the RDX disc system like LTO cartridges but with HDD.

[baber]

excuseme

but realy could not understand benefit of this backup repository
can you give an example?

BR

[foggy]

With rotated drives, you will always have one of the disks with backups somewhere offsite and ready to recover the infrastructure on a new hardware (in case your production location dies along with the currently attached drive with backups).

[baber]

i understand while select rotate drive have to define 2-3 disk for save backups ?????
is that correct ???

BR

[foggy]

Yes, this is correct.

[baber]

is that your means when select rotate drive for backup repository have to create scale-out backup repository ???
i think that is necessary to create scale out because just in this mode we can select more than repository for save backups on that and can not use feature of backup repository with rotate drive with single repository

is that correct ??

BR

[foggy]

No, scale-out repository is not supported in a rotated drives scenario. You have a single simple repository that is backed by several drives, only one of which is connected at any point in time.

[baber]

really so confused because when we create a new job select backup repository and in rotate drive you say we have single repository after backup complete i will be disjoin that repository in next backup time the backup job have to get error because can not find any repository

is that correct ??

BR

[foggy]

When you detach one disk, you attach another one and the next backup will be created on another disk. If you enable rotated drives option on the repository, the job will not error out but create a backup on the currently attached disk.

1- if i want test rotate drive in my lab can i create 3 seprate single repository and select backup repository with rotate drive for all of them and in job wizard select one of them after 1st backup has been finished edit job and select second repository and run job ?

2- if yes when run job for second time on second repository will it get incremental backup or another get full backup ??

BR

[foggy]

You do not need three repositories and edit the job each time, you need just a single one. The job will create a new full backup each time after the disk is swapped.

[baber]

2 question :

1 - imagine i have add repository with rotate drive and assign it to backup job for first backup it will be get full backup
now i disjoin repository and tomorrow another attach that repository now while job start will get backup full or incremental ?

2 - image i have add repository with rotate drive and assign it to backup job for first backup it will be get full backup
now i disjoin repository and tomorrow attach new repository to my job instead of previous repository now on this repository it will be get full or incremental backup ??

BR

[foggy]

I don't see the difference between 1 and 2, please clarify. Anyway, after switching the drive, the regular backup job will create a full backup on the next attached one. Backup copy job is able to maintain incremental chain, provided the repository is Windows.

[baber]

in 1 we disjoin the backup repository after finish 1st job that get full backup and after 1day join that repository

but in 2 disjoin the backup repository after finish 1st job that get full and after 1day add and join NEW RPOSITORY to backup job instead of previous repository

in both mode after join again backup repository which backup type will be get full or incremental ?

BR

[foggy]

Ok, if you attach the same drive again prior to the very next job run, it will create incremental backup.

[baber]

and if attach new drive another will be get full backup ??

BR

[foggy]

Correct.

[baber]

is that necessary assign rotate drive repository role to an external drive or for example can assign this role to a vm for test ??

BR

[foggy]

You can test with any repository.

[baber]

before that i think rotate drive can do such as raid 1 write backups in same time on 2 repository but you said it don't write data same time on 2 repository now is that correct rotate drive mode can not write data same time on 2 repository ?

BR

[foggy]

Correct, data is written to a single drive, but drives are switched after each job cycle.

[baber]

in previous posts you said not need edit backup job but if i want attach new repository and and swap previous repository had to edit job is that correct ??

BR

[baber]

now i wanted edit job and now use new repository when edit job is storage when chose new backup repository it show this error:

Move all backup files to the new backup repository first

now what do i have to do i select rotate drive for both of these repository
