Dots... I've removed the space character after the "/root" in the download-able script so nobody will have any more issues with this. It's seen as a dot by newer mc to show when you have free spaces after your last edited content. If you wanna see just add one or more spaces after that "/root" entry, save the file then do a Code: cat back-res | grep "/lib /lib64 /root" and see if there are dots... Thank you for your time!
Remote Backup Hello, if you mount anything remote, before de use of the backup script, and the backup dir is the remote mounted one, then you can use it as a remote backup script. You can use samba (cifs) for remote windows shares, ssh, or anything you can think of and can be mounted, even remote internet drives. I'm in the process of testing with remote ftp, but I'm not sure if it'll be good to make a separate script for this or integrate it in the backup script. For now I'm using 2 separate scripts, partially because the script which makes the ftp transfer compares the files first, then makes something like a sync, but that is not needed here... so for now I'm not sure. The simplest way now is to use a remote mounted dir for backup. For more info you can see: Linux Userland Filesystem
Hi go0ogl3, First of all thanks for your script. I have 3 production server boxes and one backup server. I have installed ISPConfig in the Multiserver setup system. So I have different services for each server. 1. Server A --->Web Server --->SVN Server 2. Server B ---> Database Server 3. Server C ---> Mail Server 4. Server D ---> Backup Server Is there a way to send the request to backup from the Backup SERVER to every other servers? I would like to load the script from the backup server and store all the backups files and directory in the Backup SERVER. Thanks
Cron runs the backup on each of my servers and writes it to the nas I have mounted on each. All you would need to do is mount your backup server instead
So, each server has a copy of the script, right? I don't understand how have I set this variable in each server: Code: BACKUPDIR="/bck/$COMPUTER"
Yes, the same script runs on each of the servers at different times The variable backupdir dictates where the backup us saved to. On my server I have a directory that mounts to the nas elsewhere on the network. So my backupdir = /mnt/backup/$computer $computer vRiable holds the name of the computer backing up.
MUltiple servers backup to special backup server Hello, The way I do it is to have a copy of the script on each of the servers and create on the backup server a dir for every server. For example: 1. on Server D I can make /backup/Server_A, /backup/Server_B, /backup/Server_C 2. mount the dir /backup/Server_A/ on Server A to dir /backup 3. mount the dir /backup/Server_B/ on Server B to dir /backup 4. mount the dir /backup/Server_C/ on Server C to dir /backup 5. define the BACKUPDIR="/backup/$COMPUTER" on servers A,B,C (you can have BACKUPDIR="/backup", but it's usefull to have a good name to your backups) 6. set up the cron jobs on the servers Good luck!
I have a server that has debian lenny and ispconfig via the perfect server howto. I am trying to migrate to a new server I have created with debian squeeze viat the perfect server howto. I make my backup and when I try to restore I get the following: oot@srv1:~/scripts# sh /root/scripts/backres.sh db all 2011-07-16 date: invalid date `07/' /root/scripts/backres.sh: line 448: [: : integer expression expected You want to restore db all to date 2011-07-16.

Hi google, Been using the script for a long time on one server and now also have it running on a remote vm server. I'm not that great with bash. Is there a simple line I could add to scp whatever files have just been written to my remote server? Like: Code: scp full_var-2011-08-16.tar.bz2 root@myip:/tmp but obviously a bit more dynamic! This script has saved my skin before!
hi google and thx for your great job! i have two problem related on server rather than script. my scenario: a VPS and a ftp backup server on remote machine with a 10GB quota on it. i have mounted the remote ftp server using curlftpfs (http://curlftpfs.sourceforge.net/) and everything seems to be ok. first problem: df show me the entire disk space on remote server (7,5TB !) and not my quota (10GB). max percentage calculation have no way to run well and the ftp space will end without a check possibility. second problem: i thgink that curlftpfs not support append to file ('>>'). i got a lot of this error Code: ./backupres: line 236: /backup/<<HOSTNAME>>/log/backup.log: Operation not supported when he try to update logfile. I think for an alternative, but i can't find a solution (manually deleting old backups!!!) third problem he not send me an email at the end of script. /tmp/tmpbck/maildata exist and he contains every log entry.
Just a quick question from a relative newbie. I've followed the perfect server - ispconfig3 on opesuse and everything is working, I've now loaded this backup script and it seems to work OK, my question is since I followed the perfect server install, it has me disable mail, I was wondering if there was a way to mail the logs to me using what ever the server is configured with (postfix,dovecot,???)? Thanks
Code: # If it's not the first day of the month we make incremental backup if [ ! -e $tmpdir/full-backup$XX.lck ] ; then log "Starting daily backup for: $YX" NEWER="--newer $FDATE" $TAR $NEWER $ARG $BACKUPDIR/$MDATE/i$XX-$FDATE.tar.bz2 $YX -X $tmpdir/excluded log "Daily backup for $YX done." else log "Lock file for $YX full backup exists!" fi Hi, I am running backup at 1 35 each night, so today, it will run at 25/08/2011 01:35 AM. NEWER="--newer $FDATE" with that line, it will check if a file is newer than 25/08/2011, and, if a file was created/modified between 24/08/2011 1:35 and 24/08/2011 23:59, it will be ignored. I think that the solution should be to work with yesterday date and not with the actual date. It will copy twice files created between 25/08/2011 00:00 and 25/08/2011 1:35 (at next backup), but right now, incremental backup is doing almost nothing. Is this correct or I forget to check something? I will try this night with line value: NEWER="--newer `date --date=yesterday +%F`" instead of: NEWER="--newer $FDATE" But, I don't know is --newer checks only creation date or modified date too... we will see this night Best regards Edit: working ok, right now inc backup working, I think that this should be a modification for the scripts (or a custom value to modify depending on script running time.
If you have a smtp mail account you can configure one of the multiple mail programs (mail, mutt, etc.) to send mail at the end of the script using that account.
Hello, the <<HOSTNAME>> is changed by you? If not that's the problem. curlftpfs does not support append to the files. The solution is to move all the appended files away (log file, there is another?) The alternative for the free space function is to get the free space with another method (repquota?) and use that value in the script... The mail problem: You need to have some mail server running (sendmail, postfix, dovecot, etc.) on your linux host to send mail with the back-res script... I'll try to post a little script to send mail using SMTP AUTH and your ISP mail server (or another) and I'll try to modify the back-res script later this month.
Hello, From the tar manual seen on http://www.gnu.org/software/tar/manual/tar.html#SEC114: The FDATE from the script is the actual date like Code: 2011-09-12 which means 2011-09-12 time 00:00 In my tests I run the script at 00:01 on 8 september for example (first minute of the 8 day) and the script archives some files modified on Code: Sep 7 23:25 and on Code: Sep 8 00:00 so I can say it's doing his job.... How you use the script the backed up files are a day older, so you'll end up archiving more files on the incremental backup. Use a simple test: create a file in cron (touch) just before the actual run of the script... or use the tar command from the command line with the required arguments.
Sorry for seen your post so late, but I'll respond maybe others will need to restore too. You can restore all of your files unpacking all the full_ archives, then all the incremental archives from that month OVER the full_ archives until the date needed. This way you'll end up with all your files, including the ones deleted from one incremental backup to another. You can use find --newer to delete unwanted files. Hope this helps others too. In your case it's possible that you have a problem with the date command and your /tmp dir is not writable or something. The way I do the restore is using an empty partition or drive or a loop device mounted in a running system, I'm adding the needed /proc and others then make it bootable (grub, lilo, etc.), then remove the drive and run the restored system.
Mail function / script for non-mail systems Hello here is a simple code for a mail function or script for the systems with mail server disabled: Code: #!/bin/bash # mailuser=`echo -n $email| base64` mailpass=`echo -n $password| base64` maildata=`$tmpdir/maildata` nc mail.server.com 25 << EOF EHLO test auth login $mailuser $mailpass mail from: $email rcpt to: $email DATA Subject: test mail telnet $maildata . quit EOF I'll try to modify the back-res script to add an option for this function. The code works only for mail servers which support smtp auth login but I hope will be enough...
smal FIX for NFS disk usage problem I noticed that if you store backup on a NFS disks when DELETE old backups NOT WORKS I have standard maxp="85" but disks was full after some days. Problem is in "function check_space" Line: Code: pfs=`df -h $BACKUPDIR | awk 'NR==2{print $5}' | cut -d% -f 1` In common disks it works cause all infos from df are in one line but in NFS mounted disks is IN TWO LINES, look: Code: # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 14G 1,7G 12G 13% / 10.246.120.212:/home/BACKUP/POCZTA 65G 65G 0 100% /home/BACKUP in this case you can user "P" switch in df, that tell df to dont do this (2 lines output for one disk). And fix will look that: Code: pfs=`df -Ph $BACKUPDIR | awk 'NR==2{print $5}' | cut -d% -f 1` please check that "df -Ph" will be works on other linux distros, and if its woks to change that. regards
Thanks for pointing this up! Thank you for help, this is because your NFS path is long but is a small fix wich I'll include in the next version, sometime in december, if my timing is ok.
