I wouldn't do that - rsync fulls take longer in wall clock time because they read all the files, but they don't take a lot more bandwidth and don't hurt you that much on remote connections which are slow anyway. You need regular fulls with rsync to rebuild the trees used for comparisons. Just make sure the days the fulls run are skewed so you have time for them to complete. You can do that by forcing a manual run to set the time. -- Les Mikesell lesmikes...@gmail.com -- ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

For any wireless laptop client, I add this to RsyncArgs: --bwlimit=256 That will set a rate limit of approximately 256 kbytes/sec, or 2 mbit.

Rob's right. Running with IncrLevels = 1 means that every incremental will download every file with a modification time newer than the last Full.

Or is it only true for the incremental runs? Smb/tar methods fulls transfer the entire content. Rsync methods compare the previous full to the current content and only transfer the differences. The difference between rsync fulls and incrementals is that incrementals completely skip files where the timestamp and length match the previous copy and fulls do a block checksum comparison in a way that does not exchange much data where the parts match. -- Les Mikesell lesmikes...@gmail.com -- ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

Rsync full backups still only transfer the differences from the last full. They run slower than incrementals because they do a block checksum comparison even on unchanged files, but don't take a lot more bandwidth. And since the previous full is the base for comparison, you don't want to go too long between fulls. If you backup both sites from both servers you should always get a complete run locally and if some of the remote targets don't complete every night the fulls will just become skewed which is probably a good idea anyway. -- Les Mikesell lesmikes...@gmail.com -- ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

Re: [BackupPC-users] Outsourcing backup
250k is plenty for this scenario. We run nightly incrementals with weekly fulls on all of our servers including the 4 remote sites. The 2 slowest of our remotes are 256k up and that is still sufficient pending you don't have alot of data change. On Tue, May 4, 2010 at 9:38 AM, Inno wrote: > It's a very good idea.

(maybe I'm not clear :-S) What I'm suggesting is that you have two complete servers, each backing up both locations, and probably nightly instead of weekly if you have the usual amount of idle time at night. Assuming that it works (which will depend on the size of the daily incremental change) you'll have a system that takes care of itself without intervention, covers the disaster scenario with less data lost, and you'll also cover the even more likely problems where someone accidentally erases a file and wants it back the next morning. -- Les Mikesell lesmikes...@gmail.com -- ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
Re: [BackupPC-users] Outsourcing backup
It's a very good idea. But with this solution I am forced to do a single full then incrementals. And I'm not sure the speed of upload will be sufficient. And configure BackupPC with : FullPeriod = -1 FullKeepCnt = 1 FullKeepCntMin = 1 FullAgeMax = 90 -- IncrPeriod = 1 IncrKeepCnt = 8 IncrKeepCntMin = 4 IncrAgeMax = 30 IncrLevels = 1, 2, 3, 4 -- If your solution is not possible, do you think mine will work without create problem in BackupPC ?

Re: [BackupPC-users] Outsourcing backup
What I would do is this: Setup backuppc for company A at the company B location Setup backuppc for company B at the company A location That way you will have total failover redundancy with no "lost weeks". So if say Company A "burns" or is robbed, etc you have the backup of the servers at company B location and vise versa. This way you are maximizing your protection. And you don't have to rely on "sneakernet" to transfer the drives. Everything is automagic. This nearly eliminates human interference. With this setup I would stagger the full backups to different days though. On Tue, May 4, 2010 at 8:55 AM, Inno wrote: > I will test it (but I want a full backup every week).

Re: [BackupPC-users] Outsourcing backup
I will test it (but I want a full backup every week). We have a connection with 250 KB/s. My goal is not to centralize backups so I wondered if my solution will be good. Imagine if the company burns or HDD breaks. For me it's better to have two HDD (at different locations) with a loss of one week if its burn. Do you understand why I want exchange between both every week and why I imagine this steps ?

Re: [BackupPC-users] Outsourcing backup
This is very true. We have 4 remote sites, 2 T1's (1.5megabit up and down) and 2 DSL (1.5megabit down x 256 kilobit up) and have a central backuppc server located in-house that backs up those 4 server and 10 more in house on the local fiber network. The only issue was the initial full on the 2 DSL connections. Since they are local to us, I was able to take the server there and run the initial full no problem. I use rsync on all the servers. The total of all the servers is over 2TB with the remote sites having about 700GB of that. So you should be good with rsync and just get the initial full onsite.

[BackupPC-users] Outsourcing backup
Hello, Can you see a problem in this thinking : We have two business building not connected between them. Servers are not the same. I would like outsourcing data. Backups are done on two Ethernet HDD. So I imagined this: Company A - Full backup on Friday night. Incremental backup every day. Company B - Full backup on Friday night. Incremental backup every day. On Friday. I go to the A. I unplug the HDD 1 (containing /var/lib/backuppc/). I go to the B. I unplug the HDD 2 (containing /var/lib/backuppc/) and I plug the HDD 1. I go back to the A. I plug the hard disk 2. Thus, one week HDD 1 is in company A and the following week in Company B. And one week HDD 2 is in Company B and the following week in the A. As HDD containing /var/lib/backuppc/ normally it doesn't create any problem for data retention ... ? What do you think ? Thank you. Innop.
