furthermore,the vm will not boot, as this files are needed for booting. This has the result, that VMware does not recognize that the VM has a snapshot, when registering that VM on the destination system. Rsync -av /path/VMName rsync will skip the current delta vmdk and the vswp file, as it cannot be accessed while being in use, these files are missing on the destination system.
On source system, create temporary snapshot with "vcbSnapshot VMid Snapname" If you want to live mirror your virtual infrastructure, you need to do the mirroring at san/storage-level or use a host-based replication solution like esxreplicator.įor most VMs i use i can live with loosing several hours of data, as these are mostly tateless systems like mail-gateway, printservers, admin-stations etc.
#FBACKUP MIRROR UPDATE#
Then create a cronjob to update it every 5 minutes, edit the crontab crontab -eĪnd add this line at the end.I´d like to get some feedback/comment about this thoughts:
#FBACKUP MIRROR PASSWORD#
Prepare your server, where the backup is stored to access the one where the original bare repository is via ssh with no password git clone -mirror the ssh password, and you have your backup, it is time to enable automatic and periodic backups. We will do this in a different server, so the backup is a real backup. To use this command and backup your bare repository in a timely basis, do this. You will be doing periodic backups automatically.You are doing the backups in another server.You have access via ssh to your bare repository.Backup a bare repository with git clone –mirror Compared to –bare, –mirror not only maps local branches of the source to local branches of the target, it maps all refs (including remote branches, notes etc.) and sets up a refspec configuration such that all these refs are overwritten by a git remote update in the target repository. Set up a mirror of the source repository. But there is another way to be sure you have a complete backup of your bare repository.
#FBACKUP MIRROR HOW TO#
Now that we know how important bare repositories are, you may want to know how to back it up? Being git almost a backup system by it own, you may assume that all clones are backups, and that is true. You can read more about this in this introduction to git article. Work on it, commit changes and push the changes back to the bare repository. All of them can clone the bare repository with: git clone
In other words, all the info needed to create a working folder in its current state or any state it may have had in the past.īare repositories are very important when a lot of people is working on the same project. In a bare repository, there is no working folder, just the history of your repository. The other part is your working folder, which is the current state of your job, as was created by git, with the info in the.
Usually contributors will clone this bare repository work with it, make changes, commit them and then upload (push) them to the bare repository.īefore going further, let's see what is a bare repository.Ī git repository is usually divided in two parts, one is the history of your project, and it is made by a lot of files in a hidden folder named. Git is great to version control your work, and it is also good that is does not have a central repository, but a distributed authority.Īnyway, when you create bare repository to sync the job between different contributors, you are somehow in a "virtual" way creating a centralized authority for git.
