Often disasters happen as a chain of unpredictable events, for example power outage during intensive I/O operations.

In case of problem with the server or a backup do not rush into action įirst conduct a full investigation to understand what happened and why. USB 3.0 sticks is pretty adequate media for the local backups.Īlternative approach is to store the initial version as a mirror and then use the tool that utilize hardlinks to de-duplicate previous (again here you need to know that they do not contain data like credit cards number, etc) and you might get 32GB of compressed Add to this some critical system directories and some user directories In this sense havingĪ local backup OS on USB stick such as Cruiser Fit (limited to 256 GB) makes perfect sense as the amount of data in "pure" OSīackup is usually minuscule (around 8GB for most versions of Linux). It does not prevent the crash, but least prolongs itĪnd good means recent (in most case the preferable is from today or, in worst, case yesterday) and readable.

After that the second disk fails and atĪ redundant disk that HP RAID controllers allow (called spare) is a definite plus in such cases. So one disk fails but no one notices that. In turn, RAID disk array hardware crash is often the result of negligence and often happens when hardware maintenance is outsourcedĪnd disks health is not monitored well. Will not lose valuable data in case of major hardware crash. Having a redundant backup, if not done not the often increases probability that your users But if and only if they do not contain sensitive That they are less then, say, 10TB) you might be able to provide a private backup for them too. If user data are small (which in modern days means Important type of backups for susadmin is also a bare-metal OS backup (rescue image). While user data should theoretically exist in corporate backup, in reality they do not (again, here Data Protector with its warts is a good example). Often one hour spent now in this area may save you several days of frantic efforts to recover the data later. This is usually a weak spot of entry level sysadmins.

Even such specialized transmission software as Aspera usually gets just 1-2 MB/sec, because it is limited by the WANīackups needs to be not only created, but tested. They get additional revenue, but which from purely technical perceptive is an unmitigated disaster for anything exceeding, say, a hundred Especially with all those experiments for backing up data into the cloud, which vendor like Amazon and Microsoft promote as Your private backup of critical data and may be OS too.Īlice in Wonderland situation created by outsourcing of IT only increases But the backup solution provided for the corporation is "universal". Only in small corporation you are also responsibleįor the backup of data. As a sysadmin you are responsible for quick and accurate restoration of the OS. Relatively small footprint, say 6GB-60GB is typical) and data which can be several hundred of terabytes (as is often the case with genomicĭata). and backup strategies are often different for OS (which is has ComplexĪfter the disaster the key question is: did your have a good backup. (which may occasionally stop working on its own as typical for HP Data Protector), but generally is not a responsible policy.
Relying of large corporation backup products can save you from fired as in this case other people are responsible for the backup As a result people just do not start working on that :-). Too complex and it is unclear what is optimal path for example for bare metal recovery of OS. But if you do not have adequate backup it can be because linux became way And that experience is impossible to fake. If you never have a hardware crash that wiped out your hard drive with important data, you can't fully appreciate the importance knowledge of which is very difficult to get from the books and articles. Along with knowledge of scripting it is a key indicator of the actual level of potential candidate. I think that the attitude of a sysadmin to backups reflects the level of professionalism of Linux/Unix system administrator better The key difference between seasoned sysadmin and a novice is the attitude toward backups.
