Bacula has a Windows client (that can be either desktop or server clients) that handles backups quite well. It utilizes VSS to create hot images of whatever you're looking to backup (works fine with Outlook AFAIK). You can set the desktop clients to use different ports than the default (9101 I think?) and port forward requests from their WAN router to each ...

I've invesitgate on the meaning of sigpipe. As described in SIGPIPE - Wikipedia, the free encyclopedia: On POSIX-compliant platforms, SIGPIPE is the signal sent to a process when it attempts to write to a pipe without a process connected to the other end. ... So I suspected that the trouble was with the ssh transport that gets disconnected. I've ...

Here comes a short small random IO primer: 7200RPM disk drives do roughly 100 IOPS. 15k RPM drives double that, about 200 IOPS. With a RAID-5 array, the best possible attainable IOPS is number of data data drives time single drive performance; as you have 3 data drives, the best possible sustained value you'll get, ever, is 300 IOPS. Use iostat -mx 5 while ...

After the first full backup, file transfers appear to be similar to those required for an incremental backup. More directory information is transfered. Incremental backups only pick up new and modified files since the last full backup. You need period full backups to track file and directory deletions. The transfer overheads are similar after the first ...

It may be faster to run rsync directly on the server. You have about a million files to access over the network. There are a couple of minimal installs of rsync that you can run. I've setup BackupPC on Windows this way. You can run a full Cygwin install, or the minimal cygwin-rsycnd install available in the BackupPC project.

As stated on the official BackupPC documentation, you can't have backup suitable for bare metal restores. This is for two reasons: BackupPC backups only files, no other disk information, like partition tables o mbr, so your disk layout is not saved. BackupPC does not backup Windows ACLs, so your NTFS file permissions are not saved I'm looking for a ...

I use ext4 for my file system. Try using the relatime (relative atime) to minimize inode updates to the directory as you delete files. Raid writes tend to be slower than reads as multiple disks must be written. This is compounded by journal writes. You might try using an external journal on a separate set of disks. Deleting files from directories with a ...

XFS deletes files, at least, in O(1), while the ext(mumble) family is in O(log n) (n being the size of the file). I don't know how that translates into deleting tons of links, but it's a start.

When revisiting this problem, I noticed that the actual users' profile folders do not inherit permissions from the parent directory. Setting this flag, or giving separate permissions on each profile folder, let's the backup user access the files.

You should check for the value of $Conf{ClientTimeout} within your configuration and increase it accordingly. Due to implementation constraints, BackupPC has little information about what is happening during the transfer of a longer file. To prevent dead transfers to hang around forever, the transfer is cancelled after $Conf{ClientTimeout} seconds - if any ...

Problem is in the capital letters, and that's why yum thinks that BackupPC is completely different package. One way to achieve what you are trying to do is: save all backuppc configurations/data remove backuppc from your server install new version from EPEL restore configuration files/data start BackupPC Configuration files (that I can see) are: ...

You should check everything on both sides of your backuppc config. first, check the server and try to increase it performance, but if you have other machines that perform better, lets skip this one. Next check the network! Network speed detected by the desktop, package size, cable quality. do some benchmarks, do a rsync (rsync-rsyncd) test of a big file. ...

The related answer might be applicable here. Namely, you don't just need to check the permissions on your ~/.ssh directory, but on your home as well. I can't help but notice that you have 750 perms on your home, whereas the default is normally 700. Try changing that, and see if it helps?

Found finally! Looking in documentation: host aliases in /etc/BackupPC/hosts adding lines- localhost.data.01 0 root localhost.data.02 0 root localhost.data.03 0 root /etc/BackupPC/pc/localhost.data.o1.pl $Conf{XferMethod} = "tar"; $Conf{TarShareName} = '/data/01'; $Conf{ClientNameAlias} = 'localhost'; same for 02,03 folders. Then backups will ...

BackupPC is very I/O intensive program and can lead to lots and lots of disk seeks. With low-end hardware there's only so much you can do, but try the following: Optimizing BackupPC itself Maximum number of concurrent backups and administrative operations plays a huge factor in BackupPC performance. Set that too high and your low-end hardware (or even ...

First try benchmarking the raid performance locally, to see if it's really the raid problem. You can even use: dd if=/dev/zero of=/your/raid/zerofile bs=16M and then after ~10 seconds killall -SIGUSR1 dd in another terminal to see the local write speed. If the speed is good enough, then try some other network method (try first with netcat (check the ...

If you or the provider has a firewall, check the session-ttl of it. As a common value is 3600... If the firewall is not in your hands, you could also use ssh with the option serveraliveinterval as mentioned here: http://unix.stackexchange.com/questions/34004/how-does-tcp-keepalive-work-in-ssh backuppc could be modified accordingly.

You could try to manually issue full backup commands one after another. Every time you do, backuppc will transfer a different chunk of the data. Once the backup succeeds you will know all your data is transferred. You could also use ssh's compression option to speed up the process and reduce iterations. Additional incremental backups should not cause any ...

You are going to need to exclude each of the folders that are giving you errors. You need to do this as the files you getting errors on are junction points (like symlinks) and smbclient cannot handle accessing them in samba-3.6.* (from what I can tell). I only want a limited backup of user data. So, the directive I am using in my [host].pl file is: ...

I believe BackupPCs implementation of the rsync protocol would not support ACLs and extended attributes anyway, so any kind of metadata stored there cannot be backed up effectively. This way, the problem of storing it does not even arise. Apparently, the rsync patches for MacOSX do contain some functionality to convert metadata [...] on the sender into an ...

Try doubling the initial backslash. Also, don't bother trying to escape the spaces with backslashes: that doesn't work. For example, the following setting (entered through the BackupPC web GUI) works for me: \\Documents and Settings Although the "Official" BackupPC documentation is generally very good, it really does fall short in this case. Fortunately, ...

I'm using Bacula to backup 2 servers for 2 years now. My Bacula server is running in a ReadyNAS duo (which has only a 186 BogoMips sparc processor and 2x1To raid disk). Bacula scales quite well and is quite robust even if your backup storage becomes full, Bacula is not easy to configure at first but at the end it allows to control your backup strategies, ...

Awhile ago, when I was attempting to replace my excellent collection of shell scripts to perform backups to a tape library with Bacula, I noticed one significant problem. The fact that it could not manage multiple tape drives for operations. This might have changed but it was a significant issue to me. What eventually happened was that the Netbackup ...

What transfer method do you use? Backuppc defaults to rsync, which should be reasonably fast on a LAN connection. So, first of all, I'd take a look at the effective network transfer speed using atop on your backup server. It should give you something far exceeding 20 MBit/s on a normal LAN. If it's slower, check if the network connection is flaky or ...

A while back, I installed BackupPC on Debian Lenny with RAID1 and LVM, and I chose to go with Reiserfs (mounted with the noatime option). I would have preferred to go with ext4, but, at the time, Lenny's ext4 support was still a bit ... new. The BackupPC FAQ recommended using Reiserfs over ext3, so that was it. Anyway, so far so good, no problems. Reiserfs ...

Here's what worked in case someone else runs into this. passwd cyg_server The assumption is that you've run ssh-host-config -y To set up sshd, take the defaults. On Win 7 if you click on the CYGWIN sshd service then look at the logon tab, you'll note that Cygwin creates a cyg_server user to run sshd under. For some bizarre reason -- at some point, ...

From my manpage: The options --server and --sender are used internally by rsync, and should never be typed by a user under normal circumstances. Some awareness of these options may be needed in certain scenarios, such as when setting up a login that can only run an rsync command. For instance, the support directory of the rsync distribution ...

The --server --sender are options that used when you are running rsync over a pipe. The rsync server is setup on the remote side so that it can do all checksum and delta-encoding magic so that you are only transferring the changed bits over the wire. This are probably not documented in the man page since they are automatically added, and usually don't need ...

You don't necessarily need to have the computers establish a VPN connection on a timed basis. BackupPC will to backups on laptops and such whenever they are reachable. Partially, completed backups will be finished next time it connects. Initial backups require transferring all the files being backed up. These will be the longest backups. Once that is ...
