Re: Backup's to DVD
As a Frisian, living at the North Sea: on clay, surrounded by reeds, I relished every single bit of spit between both long standing 'Multies' [multinationals] of the Antique. I am convinced, this poetic dispute will, in the long run, enliven even the fiercest 'Fachidiot' clinging ever tighter to his narrow subject of excellence. (Adorno's verdict: After Auschwitz one can not write poems any more. .. was answered: In truth, already before Auschwitz, Adorno couldn't write poems.) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Frisians are renowned for being creative and humorous but it is rare for their writings or conversation to be described as cute. They do have some cute looking cows though; maybe this is what you were thinking of when you were writing your post. Frisians are also real sticklers when it comes to staying on-topic. They regard it as a point of honour not to deviate from any discussion they participate in. Which is why the mail was sent to thread it joined. Like most people they are also aghast when a single word is extracted from a quote to try to make some asinine point. It disturbs the fabric of the universe when the cultural, philosophical and literary background of what the quotation means is misunderstood, misinterpreted or ignored.

CD - you can read the thing after it gathered dust for 10 years. Personal experience for both CD-R and CD-RW. An amount of information can be stored is unreasonable by today's standards. DVD - you can read the thing after it gathered dust for 5 years. Personal experience for both DVD-R and DVD-RW. An amount of information can be stored is unreasonable by today's standards. BD - no personal experience with those. USB drives - ok, but will require periodic poweron/poweroff cycle. MTBF is less as of the modern HDD, which is not much again. So, for a long-term storage one is basically left with the same thing as 20 years ago, i.e. - tapes. LTO5s go for $10 each on eBay, providing you with 1.5Tb per tape. A cost of LTO drive is painful somewhat ($1500 ), require an additional SAS or SCSI controller, but this is one-time investment basically.

We would welcome your input on this; will my family photographs or the deeds to my house be viewable on these modern devices in a thousand years time? One consideration not included in many backup evaluation matrices is a complete evaluation of the risk. Ralf has noted that solely relying on on-site backups is, um, less than optimal (oxymoronic?). On-line backups have major failings too:- ;you're relying on an entity you've never met, often in another country subject to different laws, with unknown[*1] media management and backup strategies. ;when you *need* that on-line backup restored where did you put the contacts, account details, and recovery tools? [*1] My experience is that claims and assumed expectations don't always match reality. Any backup strategy should be based on how much will it hurt if I lose it, and include careful consideration about *how* you will restore it when you need it[*2]. As PAPYRUS TECHNOLOGY notes - recovering the data is of little use if the knowledge, hardware, and software needed to make information out of the data when that backup becomes a worthwhile investment. i.e. if you backup WORM drives you'll need to separately backup the software, hardware, and necessary manuals. CDs, and even Blueray and magnetic/Flash drives won't be supported forever. As a general rule - a single backup strategy is not as useful as multiple separate ones. Risk and how much will it hurt should be the determining factors in deciding how, and how often, is appropriate. Now that we've acquired PAPYRUS TECHNOLOGY (at a knock-down price plus a small consideration to the camel train company) I'd suggest if the information is heirloom value, consider printing it on acid-free paper and placing it in a bank vault.

Because? for example lifetime of the media itself, problems to read on different kind of dvd drives and some other kind of Problems there are so many reasons why enterprise companys never use dvd's as storage medium for their data Do not confuse backup witch archive copy. I know most people do not make that difference but when people start talking about lifetime of the backup medium it is part of the discussion. however it depends how long you try to have this backup available and if you want to be sure you have a working backup Normally backups are made to recover from a disaster which is mean one will usually want to use a recent copy of the data. Sometimes a somewhat older copy is needed. One we start talking about archive data were we need to look at data that is years old and may no longer be on the current storage medium then indeed the lifetime of the backup medium does become part of the discussion. For me backup to DVD is 1) to slow and b) the medium is not large enough. I just want to dump all my data onto the backup. So I have 2 USB connected disks of which 1 is allways offsite.

I already have a pair of backup servers in different physical locations but want to add some DVD's into the mix. Those are hard to rm. ;) On-site backups are of limited value (but offer convenience). DVD backups are ideal for off-site/secured backups in your use case. Do you have a fireproof safe? Some security companies provide very cheap 24/7 access lockboxes. dkopp works well, as does cedar-backup2 and backupninja. There are also other open-source tools with similar functionality. Contrary to one opinion in this thread, most of the enterprise (and very large government departments) I've worked with *do* use DVDs for backups to some degree. They're also often used by SMEs, with bank and security lockboxes used to for secure offsite storage. Tape and online backups (usually outsourced to storage companies) are the first level of backups, but often DVDs are used as a second level of data security. The advantages being that retrieving backups from DVDs doesn't incur an additional service fee; they provide an added layer of data security, and independence from business wide backup scheduling. Belts are good, but for full pants security belt and suspenders is better. As Ralf points out - modern optical storage media is not very reliable. *If* you don't implement the same (ITIL?) practices you would/should with magnetic media - that is, check it. You should also use archive quality optical media for your backups for best results. cdck, and qpxtool are useful for checking your optical media backups before trusting them. dvdisaster is my tool of choice as it can add additional levels of error correction. As with any backup - it's of little value if kept onsite unless locked in a fire-proof safe (though I've known professionals who kept backups on the same machine they're backing up!). An additional consideration with optical media backups is age deterioration, so storage conditions and media design will determine backup rotation schedules. Note: all the tools I mentioned are in the Debian repository and IMO are as good, or better, than the commercial alternatives.

DVDs IMHO are useless as serious backup medias. Because? for example lifetime of the media itself, problems to read on different kind of dvd drives and some other kind of Problems Thanks Andre. So far, I haven't had readability problems on old CDs and DVDs. Blu-Rays seem a little squirrelly over time, but CDs and DVDs seem readable for many years. there are so many reasons why enterprise companys never use dvd's as storage medium for their data I think one of the big reasons enterprise backups avoid optical media is shear size. With DVD max 4.7GB and Blu-Ray max 25GB, a bare metal backup could involve a lot of time consuming media switching. But look at the alternatives. Tape has *always* been iffy on restorability, especially consumer grade tape devices. Backing up to a 2TB, 2.5 Western Digital external disk, about $120.00 at Costco, is a real possibility, but: 1) If you're worried about long time readability, you don't want this, because you're always going to be tempted to cannibalize old backups to make room for new ones, rather than spending another $120.00. 2) Magnetic disks tend to stop working if not spun up at regular intervals. 3) Magnetic disks can be (accidentally) erased. Not so with write-once optical media. 4) Magnetic disks are very subject to electric destruction and physical shock. Then there's cloud backup. This would theoretically be great if you could trust the commercial entity to: 1) Carefully keep you backups for later use 2) Protect your backups from being viewed by others. In practice, the only way I'd ever trust a cloud backup entity is if I had alternative copies (which I would), and the backup I submitted to them was GPG protected with maximum key size. Also, if you're like me and have upload speeds of less than 1Mbit, it's going to take forever to back up. And once again, for privacy reasons, there's no way I'd let the backup system iteratively access the files on my computer. however it depends how long you try to have this backup available and if you want to be sure you have a working backup Exactly. In practice, I do these three things: * Maintain my own, rsync driven, incremental backup server, as described at http://www.troubleshooters.com/lpm/200609/200609.htm * Back up from the backup server to Blu-Ray * Back up from the backup server to Western Digital 2.5 drives Thanks, SteveT Steve Litt* http://www.troubleshooters.com/ Troubleshooting Training * Human Performance -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

When a disc develops a bad sector, it still seems to get written to. If you rm the file and cp it back, the same place shows up as bad when you cmp the original and backup of the file. I highly recommend doing the cmp after a backup because I have seen a lot of bad copies. I use a retry loop to ensure that the backup matches the original. However, because the bad sector doesn't seem to get marked, you need to have enough free space on the BD-RE to make a second copy of the largest file, again limiting the amount you can back up. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

And assumed you never ever will experience writing issues, when using DVD-RAM, what are 4.7 GB good for? How often will you split your tar files? PS: Once the data is written, everything is fine. Reading DVD-RAM isn't an issue. DVD-RAM is opto-magnetical. The magnetical layer only could be changed, after optical heat allows this. DVD-RAM can be used the way a HDD is used, no burning software is needed. Yes, it's just a rough explanation ;), not a perfect one ;). -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

Backup's to DVD
Anyone doing anything interesting to backup data to DVD's? https://packages.debian.org/sid/dkopp ^^ Looks interesting and overall it's a pretty simple task. Suppose I could even use tar and split but just curious what others may be doing currently. FWIW, I'm mostly concerned with cloning my current backups of family photos to different media for peace of mind. I already have a pair of backup servers in different physical locations but want to add some DVD's into the mix. Those are hard to rm. ;) -- If you laid all of our laws end to end, there would be no end. -- Mark Twain -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
