backuppc documentation

If a V3 pool exists (ie: an upgrade) set this to 1. Reference counting is handled at the application level in a batch manner. The edit links are in the left navigation bar. However, we keep at least $Conf{FullKeepCntMin} full backups no matter how old they are. The default value is every hour except midnight. The -t option to BackupPC_sendEmail causes it to print the email message instead of invoking sendmail to deliver the message. Which per-host config variables a non-admin user is allowed to edit. Starting in 3.0.0 a new script bin/BackupPC_tarPCCopy can be used to assist the copy process. How do commercial backup This allows for multiple configurations at sites where there might be a combination of tape and cd/dvd backups being made. The previous v2.x version is available as BackupPC_stnd_orig.css, so if you prefer the old skin, change this to BackupPC_stnd_orig.css. In pre-FHS versions of BackupPC these files were located in __TOPDIR__/pc/HOST/config.pl. Karol 'Semper' Stelmaczonek provided the Polish translation for 3.1.0. The message is sent in plain text preceded by the MD5 digest.

Which host directories to backup when using FTP. shared private key. if you don't want to do any backups during the day it would be easier The default is a mailto: link. Setuid scripts are discouraged, so the preference is to use SCGI or mod_perl. next subject. Zero (0) means no compression. BackupPC then starts another deflate and simply appends the output file.

Ssh arguments for rsync to run ssh to connect to the client. file will still appear in the ``filled-in'' incremental dump. Email content, timing and policies are configurable. Examples: The fact this parameter is called 'TarShareName' is for historical consistency with the Smb transport options. Be aware that anyone who is allowed to The -R option recurses into directories. You will be presented with a screen that has three options: With this option the selected files and directories are restored directly back onto the host, by default in their original location. addresses. If your smb share is read-only then direct restores will fail. It maintains queues of pending backup requests, user backup requests and administrative commands. Several variables are substituted at run-time: In some cases you might need to change the broadcast address, for example if nmblookup uses 192.168.255.255 by default and you find that doesn't work, try 192.168.1.255 (or your equivalent class C address) using the -B option: If you use a WINS server and your machines don't respond to multicast NetBios requests you can use this (replace 1.2.3.4 with the IP address of your WINS server): This is preferred over multicast since it minimizes network traffic.

BackupPC is written in Perl and extracts To easily decompress a BackupPC compressed file, the script BackupPC_zcat can be found in __INSTALLDIR__/bin. You need to decide where to put the data directory, below which all the BackupPC data is stored. A powerful http/cgi user interface allows administrators to view log You will need to fill in the correct paths for ssh2 on the local host (server) and GNU tar on the client. Times at which we wake up, check all the PCs, and schedule necessary backups.

This number per archive client will be kept around before the oldest ones are pruned. How many days (runs) it takes BackupPC_nightly to traverse the entire pool.

For tar, if the exclude file contains a "/" it is assumed to be anchored at the start of the string. This page has links to the current documentation, the Github and SourceForge project pages and general information. See: You can subscribe to these lists by visiting: The backuppc-announce list is moderated and is used only for important announcements (eg: new versions). You will also need nmblookup if you are backing up linux/unix DHCP machines. Each time the configuration file is re-read a message is reported in the LOG file, so you can tail it (or view it via the CGI interface) to make sure your kill -HUP worked. Use "tar --version" or "gtar --version" to verify. from the PC. Multiple Apache's will run on different Ports (eg: 80 is standard, 8080 is a typical alternative port accessed via http://yourhost.com:8080). An external wrapper around rsync that maintains transfer data to enable two-way synchronization is drsync; see http://freshmeat.net/projects/drsync. Assuming you installed the init.d script, you can also do this with "/etc/init.d/backuppc reload". The relevant configuration settings are $Conf{TarClientPath}, $Conf{TarShareName}, $Conf{TarClientCmd}, $Conf{TarFullArgs}, $Conf{TarIncrArgs}, and $Conf{TarClientRestoreCmd}. The configuration parameters are divided into four general groups. When the next incremental happens level 6the complete set of 6 older incrementals See “Some Limitations” for more information. The new compression level will take effect only for new files that are newly compressed and added to the pool. actually extract the files from each PC client. Date display format for CGI interface. If you want to disable ping checking, set this to some program that exits with 0 status, eg: Ping command. Number of full backups to keep. One example: with 900,000 unique files in the pool, this hash gives about 7,000 repeated files, and in the worst case 500 files have the same hash. Apache can execute it (don't add ``other'' execute permission!). like a complete image of the PC (with the exception that files

Jeremy Tietsort provided the host summary table sorting feature for 3.1.0. This is used to log into the server. averages about 0.2GB. BackupPC_link. The default is off. A tab-delimited ascii table listing information about each requested archive, one per row.

But detailed technical discussions should happen on this list. The optional per-PC configuration file (__CONFDIR__/pc/$host.pl or __TOPDIR__/pc/$host/config.pl in non-FHS versions of BackupPC) is read whenever it is needed by BackupPC_dump, BackupPC_restore and others. See the documentation for more information. Each file is stored in a subdirectory X/Y/Z, where X, Y, Z are the first 3 hex digits of the MD5 digest. On this installation, this is __CGIDIR__. Please see http://backuppc.sourceforge.net/faq/limitations.html for a discussion of some of BackupPC's limitations. This can be set to a string, an array of strings, or, in the case This needs to be a big file system. Please visit and contribute to the BackupPC Wiki. Set if this backup has not been filled in with the most recent previous filled or full backup. BackupPC uses utf8 on the server for filename encoding. The backup is done using the specified XferMethod. Note: most information in this step is only relevant if you build and install BackupPC yourself. DESCARGAR LIBRO AMAR O DEPENDER DE WALTER RISO PDF. The settings of e-smith database are workable as is, they are here for documentation purpose It is recommended to make this list short as possible (you probably don't want your users saving dozens of backups) and it is essential that they can't edit any of the Cmd configuration settings, otherwise they can specify an arbitrary command that will be executed as the BackupPC user. PCs that are always or often on the network can be backed up after hours, to reduce PC, network and server load during working hours. On the other hand, if you are backing up laptops that are only intermittently connected to the network you will want to have frequent wakeups (eg: hourly) to maximize the chance that each laptop is backed up.

Alternatively, rsync can also be used on WinXX (using cygwin), and Samba could be installed on the linux or unix client to provide smb shares).

A powerful web (http/cgi) user interface allows administrators to view log One alternative is to use LDAP. So this duplication process doesn't burn a lot of pool storage space, but every file still needs to be read (to compute the MD5 digest) and "written" (really just matching/linking). BackupPC checks the modification time once during each regular wakeup. of multiple shares, a hash of strings or arrays. The CGI script will download the original file when you click on a hardlink. Any files not hardlinked eg: Flexible configuration parameters allow multiple backups to be performed in parallel, specification of which shares to backup, which directories to backup or not backup, various schedules for full and incremental backups, schedules for email reminders to users and so on. For other Online documentation for BackupPC 3.3.2. As BackupPC_tarExtract extracts the files from smbclient, it checks each

Level of verbosity in Xfer log files. Any host that has a valid NetBIOS name returned by this command (ie: matching an entry in the hosts file) will be backed up. If you are running tar locally (ie: without rsh or ssh) then remove the "+" so that the argument is no longer shell escaped. But you also want to backup the rest of the machine while the database is still running.

Rather than permit root ssh on the client, it is more secure to just allow ssh via a low-privileged user, and use sudo in $Conf{RsyncClientPath}. Here are some instructions for one way to setup ssh. than comparing the compressed new file to the pool. Total size of files that were not in the pool (as determined by BackupPC_link). specific to that host. For unix machines you can run nmbd (the NetBios name server) from the Samba distribution so that the machine responds to a NetBios name request.

In some environments, this is something like '/usr/bin/ping6'. tar file. Rikiya Yamamoto provided the Japanese translation for 3.3.0. Various programs and scripts use rsync to provide hardlinked backups. To enable the graphs, point $Conf{RrdToolPath} to the rrdtool executable. Additional navigation bar links. Both attributes $Conf{BackupFilesOnly} and $Conf{BackupFilesExclude} can be defined for the same share.

Typically this is set slightly less than an integer number of days. Any change to this file requires a separate copy of the file to be saved during backup. To use BackupPC_zcat you could give it the full file name, eg: It's your responsibility to make sure the file is really compressed: BackupPC_zcat doesn't check which backup the requested file is from. You can run "perldoc Archive::Zip" to see if this module is installed. Mod_perl provides much higher performance (around 15x) and is the best choice if your Apache was built with mod_perl support. Last month's log file. This is only needed if hosts in the conf/hosts file have the dhcp flag set. You need to have version >= 0.50. The time taken for the backup, plus the granularity of $Conf{WakeupSchedule} will make the actual backup interval a bit longer. The fourth group are settings for email reminders, and the final group contains settings for the CGI interface. Either samba's smbclient or tar over ssh/rsh/nfs piped into BackupPC_tarExtract, or rsync over ssh/rsh is run, or rsyncd is connected to, with the incoming data extracted to __TOPDIR__/pc/$host/new. If you have shares that might be empty (and therefore an empty backup is valid) you should set this flag to 0. At some sites the disk-based backup will be adequate, without a A special ShareName "*" matches any ShareName that doesn't have an explicit entry. In a future version there might be support for encryption of this password, but a private key will still have to be stored in a protected place. smbclient is from the Samba distribution. If both are set for a particular share, then $Conf{BackupFilesOnly} takes precedence and $Conf{BackupFilesExclude} is ignored. If a big file has very high compression (meaning it will use too much memory when it is inflated), BackupPC calls the flush() method, which gracefully completes the current compression.

required for fixed IP address hosts too. command. Apache needs the mod_scgi module installed, and you will need to set the same port number in the Apache configuration. Maximum number of log files we keep around in log directory. This limit will only be hit if an identical file appears at least this number of times across all the backups.
